The main objective pursued in this work is to investigate the producer gas production potential from sized biomass (sawdust and pigeon pea) by applying the air gasification technique. The size of the biomass selected for the study was in the range of 0.40-0.84 mm. An experimental study was conducted using a fluidized bed gasifier with 210 mm diameter and 1600 mm height. During the experiments, the fuel properties and the effects of operating parameters such as gasification temperatures 700 to 900 °C, equivalence ratio 0.16 to 0.46 were studied. It was concluded that substantial amounts of producer gas (up to 1110 kcal/m3) could be produced utilizing biomass such as sawdust and pigeon pea by applying this fluidization technique. For both samples, the rise of temperature till 900 °C and equivalence ratio of 0.4 favored further gasification reactions and resulted into producer gas with calorific value 1110 kcal/m3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sized%20biomass" title="sized biomass">sized biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed%20gasifier" title=" fluidized bed gasifier"> fluidized bed gasifier</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalence%20ratio" title=" equivalence ratio"> equivalence ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20profile" title=" temperature profile"> temperature profile</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20composition" title=" gas composition"> gas composition</a> </p> <a href="https://publications.waset.org/abstracts/46520/effect-of-equivalence-ratio-on-performance-of-fluidized-bed-gasifier-run-with-sized-biomass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46520.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1593</span> Evaluation of Biomass Introduction Methods in Coal Co-Gasification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruwaida%20Abdul%20Rasid">Ruwaida Abdul Rasid</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20J.%20Hughes"> Kevin J.

In co-gasification, where coal is gasified along with biomass, the biomass may be fed together with coal (co-feeding) or an independent biomass gasifier needs to be integrated with the coal gasifier. The main aim of this work is to evaluate the biomass introduction methods in coal co-gasification. This includes the evaluation of biomass concentration input (B0 to B100) and its gasification performance. A process model is developed and simulated in Aspen HYSYS, where both coal and biomass are modeled according to its ultimate analysis. It was found that the syngas produced increased with increasing biomass content for both co-feeding and independent schemes. However, the heating values and heat duties decreases with biomass concentration as more CO2 are produced from complete combustion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspen%20HYSYS" title="aspen HYSYS">aspen HYSYS</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=co-gasification%20modelling" title=" co-gasification modelling"> co-gasification modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/17080/evaluation-of-biomass-introduction-methods-in-coal-co-gasification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17080.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">409</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1592</span> Wastewater from the Food Industry: Characteristics and Possibilities of Sediments on the Basis of the Dairy Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monika%20Ga%C5%82wa-Widera">Monika Gałwa-Widera</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Kwarciak%E2%80%93Koz%C5%82owska"> Anna Kwarciak–Kozłowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucyna%20S%C5%82awik-Dembiczak"> Lucyna Sławik-Dembiczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Issues relating to management of sewage sludge from small and medium-sized wastewater treatment plants is a vital issue, which deal with such scholars as well as those directly involved in the issue of wastewater treatment and management of sedimentary.

Since this aspect has a direct impact on biomass transportation and storage, biomass availability greatly influences the operational cost. Biomass availability is more than the quantity available on a specific region; other elements such as biomass accessibility and potential play an important role. Accessibility establishes if the biomass could be extracted and conveyed easily considering factors such as biomass availability, infrastructure condition and other operational issues. On the other hand, biomass potential is defined as the capacity of a specific region to scale the usage of biomass as an energy source, move from another energy source or to switch the type of biomass to increase their biomass availability in the future. This paper defines methodologies and parameters in order to determine the biomass availability within the administrative regions of the province of Quebec; firstly by defining the forestry, agricultural, municipal solid waste and energy crop biomass availability per administrative region, next its infrastructure accessibility and lastly defining the region potential. Thus, these data are processed to create a biomass availability matrix allowing to define the overall biomass availability per region and to determine the most optional candidates for bioenergy plant location. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=availability" title=" availability"> availability</a>, <a href="https://publications.waset.org/abstracts/search?q=bioenergy" title=" bioenergy"> bioenergy</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility" title=" accessibility"> accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20potential" title=" biomass potential"> biomass potential</a> </p> <a href="https://publications.waset.org/abstracts/4941/biomass-availability-matrix-methodology-to-define-high-level-biomass-availability-for-bioenergy-purposes-a-quebec-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4941.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1590</span> Biomass For Energy In Improving Sustainable Economic Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dahiru%20Muhammad">Dahiru Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Danladi"> Muhammad Danladi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yahaya"> Muhammad Yahaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu%20Garba"> Adamu Garba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper put forward the potentialities of biomass for energy as divers means of sustainable economic development.

Renewable energy, mainly biomass, is found to be one feasible solution as it is inexhaustible and clean energy source all over the world. Out of various methods, thermo chemical conversion is considered to be the most common and convenient method to extract energy from biomass. The thermo-chemical methods that are employed are gasification, liquefaction and combustion. On gasification biomass yields biogas, on liquefaction biomass yields bio-oil and on combustion biomass yields bio-char. Any attempt to biomass gasification, liquefaction or combustion calls for a good understanding of biomass pyrolysis. So, Irrespective of the method used the first step towards the thermo-chemical treatment of biomass is pyrolysis. Pyrolysis mainly converts the solid mass into liquid with gas and residual char as the byproducts. Liquid is used for the production of heat, power and many other chemicals whereas the gas and char can be used as fuels to generate heat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidisation" title=" fluidisation"> fluidisation</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title=" pyrolysis"> pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/24385/modelling-and-simulation-of-biomass-pyrolysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24385.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1587</span> The Temperature Influence for Gasification in the Advanced Biomass Gasifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narsimhulu%20Sanke">Narsimhulu Sanke</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20N.%20Reddy"> D.

This work was planned with four replications at a Completely Randomized Block Design in 2011-2012 growing season. In the study, root biomass growth was evaluated at stages of stem elongation, complete of anthesis and full grain maturity. Results showed that there were significant differences between cultivars grown at dry and irrigated lands in all growth stages in terms of root biomass (P < 0.01). According to research results, all of growth stages, dry typed-bread and durum wheats generally had higher root biomass than irrigated typed-cultivars, furthermore that dry typed-barley cultivar, had higher root biomass at GS 31 and GS 69, however lower at GS 92 than Larende. In all cultivars, root biomass increased between GS 31 and GS 69 so that dry typed-cultivars had more root biomass increase than irrigated typed-cultivars. Root biomass of bread wheat increased between GS 69 and GS 92, however root biomass of barley and durum wheat decreased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bread%20and%20durum%20wheat" title="bread and durum wheat">bread and durum wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=barley" title=" barley"> barley</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20biomass" title=" root biomass"> root biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20growth%20stage" title=" different growth stage"> different growth stage</a> </p> <a href="https://publications.waset.org/abstracts/20561/root-biomass-growth-in-different-growth-stages-of-wheat-and-barley-cultivars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20561.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">606</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1585</span> Research Facility Assessment for Biomass Combustion in Moving Grate Furnaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Gallucci">Francesco Gallucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariangela%20Salerno"> Mariangela Salerno</a>, <a href="https://publications.waset.org/abstracts/search?q=Ettore%20Guerriero"> Ettore Guerriero</a>, <a href="https://publications.waset.org/abstracts/search?q=Manfredi%20Amalfi"> Manfredi Amalfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giancarlo%20Chiatti"> Giancarlo Chiatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Fulvio%20Palmieri"> Fulvio Palmieri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper deals with the experimental activities on a biomass combustion test-bed.

Fluidised bed gasifier has the potential to be effectively sized for medium or large scale. This study investigated the use of fuel briquettes produced from blends of rice husks and corn cobs biomass residues, in a bubbling fluidised bed gasifier. The study adopted a combination of numerical equations and Aspen Plus simulation software to predict the product gas (syngas) composition based on briquette's density and biomass composition (blend ratio of rice husks to corn cobs). The Aspen Plus model was based on an experimentally validated model from the literature. The results based on a briquette size of 32 mm diameter and relaxed density range of 500 to 650 kg/m3 indicated that fluidisation air required in the gasifier increased with an increase in briquette density, and the fluidisation air showed to be the controlling factor compared with the actual air required for gasification of the biomass briquettes. The mass flowrate of CO2 in the predicted syngas composition, increased with an increase in the air flow rate, while CO production decreased and H2 was almost constant. The H2/CO ratio for various blends of rice husks and corn cobs did not significantly change at the designed process air, but a significant difference of 1.0 for H2/CO ratio was observed at higher air flow rate, and between 10/90 to 90/10 blend ratio of rice husks to corn cobs. This implies the need for further understanding of biomass variability and hydrodynamic parameters on syngas composition in biomass briquette gasification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspen%20plus" title="aspen plus">aspen plus</a>, <a href="https://publications.waset.org/abstracts/search?q=briquettes" title=" briquettes"> briquettes</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidised%20bed" title=" fluidised bed"> fluidised bed</a>, <a href="https://publications.waset.org/abstracts/search?q=gasification" title=" gasification"> gasification</a>, <a href="https://publications.waset.org/abstracts/search?q=syngas" title=" syngas"> syngas</a> </p> <a href="https://publications.waset.org/abstracts/31740/fluidised-bed-gasification-of-multiple-agricultural-biomass-derived-briquettes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31740.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">457</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1582</span> Removal of Tar Contents in Syngas by Using Different Fuel from Downdraft Biomass Gasification System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Awais">Muhammad Awais</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Li"> Wei Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Anjum%20Munir"> Anjum Munir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomass gasification is a process of converting solid biomass ingredients into a combustible gas which can be used in electricity generation. Regardless of their applications in many fields, biomass gasification technology is still facing many cleaning issues of syngas. Tar production in biomass gasification process is one of the biggest challenges for this technology. The aimed of this study is to evaluate the tar contents in syngas produced from wood chips, corn cobs, coconut shells and mixture of corn cobs and wood chips as biomass fuel and tar removal efficiency of different cleaning units integrated with gassifier. Performance of different cleaning units, i.e., cyclone separator, wet scrubber, biomass filter, and auxiliary filter was tested under two biomass fuels. Results of this study indicate that wood chips produced less tar of 1736 mg/Nm³ as compared to corn cobs which produced tor 2489 mg/Nm³. It is also observed that coconut shells produced a high amount of tar. It was observed that when wood chips were used as a fuel, syngas tar contents were reduced from 6600 to 112 mg/Nm³ while in case of corn cob, they were reduced from 7500 mg/Nm³ to 220 mg/Nm³. Overall tar removal efficiencies of cyclone separator, wet scrubber, biomass filter, and auxiliary filter was 72%, 63%, 74%, 35% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=gasification" title=" gasification"> gasification</a>, <a href="https://publications.waset.org/abstracts/search?q=tar" title=" tar"> tar</a>, <a href="https://publications.waset.org/abstracts/search?q=cleaning%20system" title=" cleaning system"> cleaning system</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20filter" title=" biomass filter"> biomass filter</a> </p> <a href="https://publications.waset.org/abstracts/104807/removal-of-tar-contents-in-syngas-by-using-different-fuel-from-downdraft-biomass-gasification-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104807.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1581</span> Application of Biomass Ashes as Supplementary Cementitious Materials in the Cement Mortar Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20%C5%A0upi%C4%87">S.

Biomass is one of the largest renewable energy sources, and Serbia is among the top European countries in terms of the amount of available and unused biomass. Substituting cement with the ashes obtained by the combustion of biomass would reduce the negative impact of concrete industry on the environment and would provide a waste valorization by the reuse of this type of by-product in mortars and concretes manufacture. The study contains data on physical properties, chemical characteristics and pozzolanic properties of obtained biomass ashes: wheat straw ash and mixture of wheat and soya straw ash in Serbia, which were, later, used as supplementary cementitious materials in preparation of mortars. Experimental research of influence of biomass ashes on physical and mechanical properties of cement mortars was conducted. The results indicate that the biomass ashes can be successfully used in mortars as substitutes of cement without compromising their physical and mechanical performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=ash" title=" ash"> ash</a>, <a href="https://publications.waset.org/abstracts/search?q=cementitious%20material" title=" cementitious material"> cementitious material</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a> </p> <a href="https://publications.waset.org/abstracts/83379/application-of-biomass-ashes-as-supplementary-cementitious-materials-in-the-cement-mortar-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83379.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1580</span> Physico-Chemical Characterization of an Algerian Biomass: Application in the Adsorption of an Organic Pollutant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djelloul%20Addad">Djelloul Addad</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Belkhadem%20Mokhtari"> Fatiha Belkhadem Mokhtari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to study the retention of methylene blue (MB) by biomass.

The effect of certain physicochemical parameters on the adsorption of MB is studied (effect of the pH). This study shows that the increase in the initial concentration of MB leads to an increase in the adsorbed quantity. The adsorption efficiency of MB decreases with increasing biomass mass. The adsorption kinetics show that the adsorption is rapid, and the maximum amount is reached after 120 min of contact time. It is noted that the pH has no great influence on the adsorption. The isotherms are best modelled by the Langmuir model. The adsorption kinetics follow the pseudo-second-order model. The thermodynamic study of adsorption shows that the adsorption is spontaneous and exothermic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dyes" title="dyes">dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=methylene%20blue" title=" methylene blue"> methylene blue</a>, <a href="https://publications.waset.org/abstracts/search?q=langmuir" title=" langmuir"> langmuir</a> </p> <a href="https://publications.waset.org/abstracts/184434/physico-chemical-characterization-of-an-algerian-biomass-application-in-the-adsorption-of-an-organic-pollutant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1579</span> Oxygen Enriched Co-Combustion of Sub-Bituminous Coal/Biomass Waste Fuel Blends</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaouki%20Ghenai">Chaouki Ghenai </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational Fluid Dynamic analysis of co-combustion of coal/biomass waste fuel blends is presented in this study.

Sub-bituminous Nigerian coal with calorific value of 32.51 MJ/kg and sawdust (biomass) with calorific value of 16.68 MJ/kg is used in this study. Coal/Biomass fuel blends co-combustion is modeled using mixture fraction/pdf approach for non-premixed combustion and Discrete Phase Modeling (DPM) to predict the trajectories and the heat/mass transfer of the fuel blend particles. The results show the effects of oxygen concentrations and biomass portions in the coal/biomass fuel blends on the gas and particles temperatures, the flow field, the devolitization and burnout rates inside the combustor and the CO2 and NOX emissions at the exit from the combustor.

Hence, tremendous efforts have been made to develop technologies capable of transforming biomass into suitable forms of bio-fuel. One of the viable technologies is gasifying biomass in supercritical water (SCW), a green medium for reactions. While previous studies overwhelmingly selected glucose as a model compound for biomass, the present study adopted fructose for the sake of comparison. The gasification of fructose in SCW was investigated experimentally to evaluate the applicability of supercritical water processes to biomass gasification. Experiments were conducted with an autoclave reactor. Gaseous product mainly consists of H2, CO, CO2, CH4 and C2H6. The effect of two major operating parameters, the reaction temperature (673-873 K) and the dosage of oxidizing agent (0-0.5 stoichiometric oxygen), on the product gas composition, yield and heating value was also examined, with the reaction pressure fixed at 25 MPa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=fructose" title=" fructose"> fructose</a>, <a href="https://publications.waset.org/abstracts/search?q=gasification" title=" gasification"> gasification</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20water" title=" supercritical water "> supercritical water </a> </p> <a href="https://publications.waset.org/abstracts/9573/the-gasification-of-fructose-in-supercritical-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9573.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1577</span> Data Collection with Bounded-Sized Messages in Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Kyung%20An">Min Kyung An</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the data collection problem in Wireless Sensor Networks (WSNs) adopting the two interference models: The graph model and the more realistic physical interference model known as Signal-to-Interference-Noise-Ratio (SINR).

Because we detect the presence of cross-sectional dependence and heterogeneity across countries for the analyzed data, we use panel estimation methods robust to cross-sectional dependence and heterogeneity. The CADF and the CIPS panel unit root tests indicate that carbon emissions, real income and biomass energy consumption are stationary at the first-differences. The LM bootstrap panel cointegration test shows that the analyzed variables are cointegrated. Results from the panel group-mean DOLS and the panel group-mean FMOLS estimators show that increase in biomass energy consumption decreases CO2 emissions and the EKC hypothesis is validated. Therefore, countries are advised to boost their production and increase the use of biomass energy for lower level of emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20energy" title="biomass energy">biomass energy</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20emissions" title=" CO2 emissions"> CO2 emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=EKC%20model" title=" EKC model"> EKC model</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-sectional%20dependence" title=" cross-sectional dependence"> cross-sectional dependence</a> </p> <a href="https://publications.waset.org/abstracts/52904/analyzing-the-effects-of-real-income-and-biomass-energy-consumption-on-carbon-dioxide-co2-emissions-empirical-evidence-from-the-panel-of-biomass-consuming-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52904.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1575</span> Allometric Models for Biomass Estimation in Savanna Woodland Area, Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullahi%20Jibrin">Abdullahi Jibrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Aishetu%20Abdulkadir"> Aishetu Abdulkadir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of allometric models is crucial to accurate forest biomass/carbon stock assessment. The aim of this study was to develop a set of biomass prediction models that will enable the determination of total tree aboveground biomass for savannah woodland area in Niger State, Nigeria. Based on the data collected through biometric measurements of 1816 trees and destructive sampling of 36 trees, five species specific and one site specific models were developed. The sample size was distributed equally between the five most dominant species in the study site (Vitellaria paradoxa, Irvingia gabonensis, Parkia biglobosa, Anogeissus leiocarpus, Pterocarpus erinaceous). Firstly, the equations were developed for five individual species. Secondly these five species were mixed and were used to develop an allometric equation of mixed species. Overall, there was a strong positive relationship between total tree biomass and the stem diameter. The coefficient of determination (R2 values) ranging from 0.93 to 0.99 P < 0.001 were realised for the models; with considerable low standard error of the estimates (SEE) which confirms that the total tree above ground biomass has a significant relationship with the dbh. The F-test value for the biomass prediction models were also significant at p < 0.001 which indicates that the biomass prediction models are valid. This study recommends that for improved biomass estimates in the study site, the site specific biomass models should preferably be used instead of using generic models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allometriy" title="allometriy">allometriy</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20stock" title=" carbon stock "> carbon stock </a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20equation" title=" regression equation"> regression equation</a>, <a href="https://publications.waset.org/abstracts/search?q=woodland" title=" woodland"> woodland</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory "> inventory </a> </p> <a href="https://publications.waset.org/abstracts/27294/allometric-models-for-biomass-estimation-in-savanna-woodland-area-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27294.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">448</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1574</span> Atmospheric Fluid Bed Gasification of Different Biomass Fuels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Lis%C3%BD">Martin Lisý</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Bal%C3%A1%C5%A1"> Marek Baláš</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20%C5%A0pil%C3%A1%C4%8Dek"> Michal Špiláček</a>, <a href="https://publications.waset.org/abstracts/search?q=Zden%C4%9Bk%20Sk%C3%A1la"> Zdeněk Skála</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper shortly describes biomass types and growing amount in the Czech Republic.

Carbon dioxide is one of greenhouse gases. It is considered to be a main reason for global warming. Deforestation is a key source of the increase in carbon dioxide whereas forests such as mangroves assist in removing carbon dioxide from atmosphere by storing them in its biomass and soil. By using Kauffman and Donato methodology, above- and below-ground biomass and carbon stored in UAE’s natural mangroves were quantified. Carbon dioxide equivalent (CO2eq) released to the atmosphere was then estimated in case of mangroves deforestation in the UAE. The results show that the mean total biomass of mangroves in the UAE ranged from 15.75 Mg/ha to 3098.69 Mg/ha. The estimated CO2eq released upon deforestation in the UAE was found to have a minimal effect on the temperature increase and thus global warming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20stored%20in%20biomass" title="carbon stored in biomass">carbon stored in biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=mangrove%20deforestation" title=" mangrove deforestation"> mangrove deforestation</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20change" title=" temperature change"> temperature change</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20Arab%20Emirate" title=" United Arab Emirate"> United Arab Emirate</a> </p> <a href="https://publications.waset.org/abstracts/26138/carbon-storage-in-natural-mangrove-biomass-its-destruction-and-potential-impact-on-climate-change-in-the-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26138.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1568</span> Enzymatic Saccharification of Dilute Alkaline Pre-treated Microalgal (Tetraselmis suecica) Biomass for Biobutanol Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Kassim">M.

In this study, enzymatic saccharification of dilute potassium hydroxide (KOH) pre-treated Tetraselmis suecica biomass was carried out by using cellulase enzyme obtained from Trichoderma longibrachiatum. Initially, the pre-treatment conditions were optimised by changing alkali reagent concentration, retention time for reaction, and temperature. The T. suecica biomass after pre-treatment was also characterized using Fourier Transform Infrared Spectra and Scanning Electron Microscope. These analyses revealed that the functional group such as acetyl and hydroxyl groups, structure and surface of T. suecica biomass were changed through pre-treatment, which is favourable for enzymatic saccharification process. Comparison of enzymatic saccharification of untreated and pre-treated microalgal biomass indicated that higher level of reducing sugar can be obtained from pre-treated T. suecica. Enzymatic saccharification of pre-treated T. suecica biomass was optimised by changing temperature, pH, and enzyme concentration to solid ratio ([E]/[S]). Highest conversion of carbohydrate into reducing sugar of 95% amounted to reducing sugar yield of 20 (wt%) from pre-treated T. suecica was obtained from saccharification, at temperature: 40°C, pH: 4.5 and [E]/[S] of 0.1 after 72 h of incubation. Hydrolysate obtained from enzymatic saccharification of pretreated T. suecica biomass was further fermented into biobutanol using Clostridium saccharoperbutyliticum as biocatalyst. The results from this study demonstrate a positive prospect of application of dilute alkaline pre-treatment to enhance enzymatic saccharification and biobutanol production from microalgal biomass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgal%20biomass" title="microalgal biomass">microalgal biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20saccharification" title=" enzymatic saccharification"> enzymatic saccharification</a>, <a href="https://publications.waset.org/abstracts/search?q=biobutanol" title=" biobutanol"> biobutanol</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/12717/enzymatic-saccharification-of-dilute-alkaline-pre-treated-microalgal-tetraselmis-suecica-biomass-for-biobutanol-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12717.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">385</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1567</span> The Effects of Stand Density, Standards and Species Composition on Biomass Production in Traditional Coppices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marek%20Mejst%C5%99%C3%ADk">Marek Mejstřík</a>, <a href="https://publications.waset.org/abstracts/search?q=Radim%20Matula"> Radim Matula</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20%C5%A0r%C3%A1mek"> Martin Šrámek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional coppices and coppice-with-standards were widely used throughout Europe and Asia for centuries but were largely abandoned in the second half of the 19th century, especially in central and northwestern Europe. In the last decades, there has been a renewed interest in traditional coppicing for nature conservation and most often, for rapid woody biomass production. However, there is little information on biomass productivity of traditional coppices and what affects it. Here, we focused on the effects of stand density, standards and tree species composition on sprout biomass production in newly restored coppices in the Czech Republic. We measured sprouts and calculated sprout biomass 7 years after the harvest from 2013 resprouting stumps in two 4 ha experimental plots. Each plot was divided into 64 subplots with different densities of standards and sprouting stumps. Total sprout biomass declined with increasing density of standards, but the effect of standards differed significantly among studied species. Whereas increasing density of standards decreased sprout biomass in Quercus petraea and Carpinus betulus, it did not affect sprout biomass productivity in Acer campestre and Tilia cordata. Sprout biomass on stand-level increased linearly with an increasing number of sprouting stumps and we observed no leveling of this relationship even in the highest densities of stumps. We also found a significant shift in tree species composition with the steeply declining relative abundance of Quercus in favor of other studied tree species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20coppice" title="traditional coppice">traditional coppice</a>, <a href="https://publications.waset.org/abstracts/search?q=coppice%20with%20standards" title=" coppice with standards"> coppice with standards</a>, <a href="https://publications.waset.org/abstracts/search?q=sprout%20biomass" title=" sprout biomass"> sprout biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20management" title=" forest management"> forest management</a> </p> <a href="https://publications.waset.org/abstracts/147514/the-effects-of-stand-density-standards-and-species-composition-on-biomass-production-in-traditional-coppices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1566</span> Challenges of Sustainable Development of Small and Medium-Sized Enterprises in Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kharaishvili%20Eteri">Kharaishvili Eteri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article highlights the importance of small and medium-sized enterprises in achieving the goals of sustainable development of the economy and increasing the well-being of the population.

Therefore, it is important to identify the challenges that will ensure compliance with the goals and requirements of sustainable development of small and mediumsized enterprises. Objectives. The goal of the study is to reveal the challenges of sustainable development in small and medium-sized enterprises in Georgia and to develop recommendations for strategic development opportunities. Methodologies The challenges of sustainable development of small and medium-sized enterprises are investigated with the following methodology: bibliographic research of scientific works and reports of organizations is carried out; Based on the grouping of sustainable development goals, the performance indicators of these goals are studied; Differences with respect to the corresponding indicators of European countries are determined by the comparison method; The matrix scheme establishes the conditions and tools for sustainable development; Challenges of sustainable development are identified by factor analysis. Contributions Trends in the sustainable development of small and medium-sized enterprises are studied from the point of view of economic, social and environmental factors; To ensure sustainability, the conditions and tools for sustainable development are established (certified supply chains and global markets, allocation of financial resources necessary for sustainable development, proper public procurement, highly qualified workforce, etc.); Several main challenges have been identified in the sustainable development of small and medium-sized enterprises, including: limited internal resources; Institutional factors, especially vague and imperfect regulations, bureaucracy; low level of investments; Low level of qualification of human capital and others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20and%20medium-sized%20enterprises" title="small and medium-sized enterprises">small and medium-sized enterprises</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=conditions%20of%20sustainable%20development" title=" conditions of sustainable development"> conditions of sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20directions%20of%20sustainable%20development." title=" strategic directions of sustainable development."> strategic directions of sustainable development.</a> </p> <a href="https://publications.waset.org/abstracts/161645/challenges-of-sustainable-development-of-small-and-medium-sized-enterprises-in-georgia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161645.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1565</span> A Correlative Study of Heating Values of Saw Dust and Rice Husks in the Thermal Generation of Electricity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Danladi">Muhammad Danladi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Bura%20Garba"> Muhammad Bura Garba</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yahaya"> Muhammad Yahaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Dahiru%20Muhammad"> Dahiru Muhammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomass is one of the primary sources of energy supply, which contributes to about 78% of Nigeria. In this work, a comparative analysis of the heating values of sawdust and rice husks in the thermal generation of electricity was carried out. In the study, different masses of biomass were used and the corresponding electromotive force in millivolts was obtained. A graph of e.m.f was plotted against the mass of each biomass and a gradient was obtained. Bar graphs were plotted to represent the values of e.m.f and masses of the biomass. Also, a graph of e.m.f against eating values of sawdust and rice husks was plotted, and in each case, as the e.m.f increases also, the heating values increases. The result shows that saw dust with 0.033Mv/g gradient and 3.5 points of intercept had the highest gradient, followed by rice husks with 0.026Mv/g gradient and 2.6 points of intercept. It is, therefore, concluded that sawdust is the most efficient of the two types of biomass in the thermal generation of electricity. <p class="card-text"><strong>Keywords:</strong> <a
