The more useful reactions produce <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Alkane" title="Alkane">alkanes</a> as follows:</p> <dl> <dd>(2<i>n</i> + 1) H<sub>2</sub> + <i>n</i> CO → C<sub><i>n</i></sub>H<sub>(2<i>n</i>+2)</sub> + <i>n</i> H<sub>2</sub>O</dd> </dl> <p>where <i>n</i> is typically 10-20.

Higher temperatures lead to faster reactions and higher conversion rates but also tend to favor methane production. For this reason, the temperature is usually maintained at the low to middle part of the range. Increasing the pressure leads to higher conversion rates and also favors formation of long-chained <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Alkane" title="Alkane">alkanes</a>, both of which are desirable. Typical pressures range from one to several tens of atmospheres. Even higher pressures would be favorable, but the benefits may not justify the additional costs of high-pressure equipment, and higher pressures can lead to catalyst deactivation via coke formation.</p> <p>A variety of synthesis-gas compositions can be used. For cobalt-based catalysts the optimal H<sub>2</sub>:CO ratio is around 1.8–2.1. Iron-based catalysts promote the water-gas-shift reaction and thus can tolerate lower ratios. This reactivity can be important for synthesis gas derived from coal or biomass, which tend to have relatively low H<sub>2</sub>:CO ratios (<1).</p> <h3><span class="mw-headline" id="Design_of_the_Fischer-Tropsch_process_reactor">Design of the Fischer-Tropsch process reactor</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=6" title="Edit section: Design of the Fischer-Tropsch process reactor">edit</a><span class="mw-editsection-bracket">]</span></span></h3> <p>Efficient removal of heat from the reactor is basic need of the Fischer-Tropsch reactors since these reactions are characterized by high exothermicity. Four types of reactors are discussed:</p> <p><b>Multi tubular fixed bed reactor:</b> This type of reactor contains number of tubes with small diameter. These tubes contains catalyst and are surrounded by boiling water which removes the heat of reaction. Fixed Bed Reactor is suitable to operate at low temperatures and has upper temperature limit of 530 K. Excess temperature leads to carbon deposition and hence blockage of the reactor. Since large amounts of products formed are in liquid state this type reactor can also be termed as trickle flow reactor system.</p> <p><b>Entrained flow reactor:</b> Important requirement of the reactor for Fischer Tropsch process is to remove the heat of the reaction. This type of reactor contains two banks of heat exchangers which removes heat, remaining is removed by products and recycle of the system.The formation of heavy waxes should be avoided since this condenses on the catalyst and forms agglomeration.This leads to fluidization.Hence risers are operated over 570 K.</p> <p><b>Slurry Reactors:</b> Heat removal is done by internal cooling coils. Synthesis gas is bubbled through the waxy products and finely divided catalyst which is suspended in the liquid medium.This also provides agitation of the contents of the reactor. Catalyst particle size reduces diffusional heat and mass transfer limitations.Lower temperature in reactor leads to more viscous product and higher (> 570 K) gives undesirable products spectrum. However separation of the product from catalyst is a problem.</p> <p><b>Fluid-bed- and circulating catalyst(riser) reactors:</b> These are used for high temperature Fischer Tropsch synthesis (nearly 340<sup>o</sup>C) to produce low molecular weight olefinic hydrocarbons on alkalised fused iron catalysts. The fluid bed technology (as adapted from catalytic cracking of heavy petroleum distillates)was introduced by Hydrocarbon Research in the years 1946–1950 and named ‘Hydrocol’ process. A large scale Fischer Tropsch Hydrocol plant (3,50,000 tons per annum) operated during the years 1951–1957 in Brownsville, Texas. Due to technical problems and lacking economy at increasing petroleum availability this development was discontinued. Fluid bed Fischer Tropsch synthesis has recently been very successfully reinvestigated by Sasol. One reactor with a capacity of 5,00,000 tons per annum is now in operation and even larger ones are being built (nearly 8,50,000 tons per annum). The process is now used for mainly olefins C<sub>2</sub>, C<sup>7</sup> production. This new development can be regarded as an important progress in Fischer Tropsch technology. A high temperature process with a circulating iron catalyst (‘Circulating fluid bed’, ‘riser reactor’, ‘entrained catalyst process’) was introduced by the Kellogg Company and a respective plant built at Sasol in 1956. It was improved by Sasol for successful operation. At Secunda, South Africa, Sasol has operated 16 advanced reactors of this type with a capacity of Approx. 3,30,000 tons per annum each. Now the circulating catalyst process is being replaced by the superior Sasol advanced fluid bed technology. Early experiments with cobalt-catalyst particles suspended in oil have been performed by Fischer. The bubble column reactor with a powdered iron slurry catalyst and a CO-rich syngas was particularly developed to pilot plant scale by Kölbel at the Rheinpreuben Company in 1953. Recently (since 1990) low temperature Fischer Tropsch slurry processes are under investigation for the use of iron and cobalt catalysts, particularly for the production of a hydrocarbon wax, to be used as such, or to be hydrocracked and isomerised to mainly Diesel fuel by Exxon and Sasol. Today slurry phase (bubble column) low temperature Fischer Tropsch synthesis is regarded by many authors as the most efficient process for Fischer Tropsch clean Diesel production. This Fischer Tropsch technology is also under development by the Statoil Company (Norway) for use on a vessel to convert associated gas at offshore oil fields into a hydrocarbon liquid. <sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span>[</span>5<span>]</span></a></sup></p> <h3><span class="mw-headline" id="Product_distribution">Product distribution</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=7" title="Edit section: Product distribution">edit</a><span class="mw-editsection-bracket">]</span></span></h3> <p>In general the product distribution of hydrocarbons formed during the Fischer–Tropsch process follows an Anderson–Schulz–Flory distribution,<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span>[</span>6<span>]</span></a></sup> which can be expressed as:</p> <dl> <dd><i>W</i><sub><i>n</i></sub>/<i>n</i> = (1 − α)<sup>2</sup>α<sup><i>n</i>−1</sup></dd> </dl> <p>where <i>W</i><sub><i>n</i></sub> is the weight fraction of hydrocarbons containing <i>n</i> carbon atoms. <i>α</i> is the chain growth probability or the probability that a molecule will continue reacting to form a longer chain. In general, α is largely determined by the catalyst and the specific process conditions.</p> <p>Examination of the above equation reveals that methane will always be the largest single product so long as alpha is less than 0.5; however, by increasing α close to one, the total amount of methane formed can be minimized compared to the sum of all of the various long-chained products. Increasing α increases the formation of long-chained hydrocarbons. The very long-chained hydrocarbons are waxes, which are solid at room temperature. Therefore, for production of liquid transportation fuels it may be necessary to crack some of the Fischer–Tropsch products. In order to avoid this, some researchers have proposed using zeolites or other catalyst substrates with fixed sized pores that can restrict the formation of hydrocarbons longer than some characteristic size (usually n<10). This way they can drive the reaction so as to minimize methane formation without producing lots of long-chained hydrocarbons. Such efforts have met with only limited success.</p> <h3><span class="mw-headline" id="Catalysts">Catalysts</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=8" title="Edit section: Catalysts">edit</a><span class="mw-editsection-bracket">]</span></span></h3> <p>A variety of <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Catalyst" title="Catalyst" class="mw-redirect">catalysts</a> can be used for the Fischer–Tropsch process, but the most common are the <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Transition_metal" title="Transition metal">transition metals</a> <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Cobalt" title="Cobalt">cobalt</a>, <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Iron" title="Iron">iron</a>, and <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Ruthenium" title="Ruthenium">ruthenium</a>. <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Nickel" title="Nickel">Nickel</a> can also be used, but tends to favor methane formation (“<a href="/web/20150213003247/http://en.wikipedia.org/wiki/Methanation" title="Methanation">methanation</a>”).</p> <h4><span class="mw-headline" id="Cobalt">Cobalt</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=9" title="Edit section: Cobalt">edit</a><span class="mw-editsection-bracket">]</span></span></h4> <p>Cobalt-based catalysts are highly active, although iron may be more suitable for certain applications. Cobalt catalysts are more active for Fischer–Tropsch synthesis when the feedstock is natural gas. Natural gas has a high hydrogen to carbon ratio, so the water-gas-shift is not needed for cobalt catalysts. Iron catalysts are preferred for lower quality feedstocks such as coal or biomass. Synthesis gases derived from these hydrogen-poor feedstocks has a low-hydrogen-content and require the water-gas-shift reaction. Unlike the other metals used for this process (Co, Ni, Ru), which remain in the metallic state during synthesis, iron catalysts tend to form a number of phases, including various oxides and <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Carbide" title="Carbide">carbides</a> during the reaction. Control of these phase transformations can be important in maintaining catalytic activity and preventing breakdown of the catalyst particles.</p> <p>In addition to the active metal the catalysts typically contain a number of "promoters," including potassium and copper. Group 1 alkali metals, including potassium, are a poison for cobalt catalysts but are promoters for iron catalysts. Catalysts are supported on high-surface-area binders/supports such as <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Silica" title="Silica" class="mw-redirect">silica</a>, <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Alumina" title="Alumina" class="mw-redirect">alumina</a>, or <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Zeolites" title="Zeolites" class="mw-redirect">zeolites</a>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span>[</span>7<span>]</span></a></sup> Promotors also have an important influence on activity. Alkali metal oxides and copper are common promotors, but the formulation depends on the primary metal, iron vs cobalt.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span>[</span>8<span>]</span></a></sup> Alkali oxides on cobalt catalysts generally cause activity to drop severely even with very low alkali loadings. C5+ and CO2 selectivity increase while methane and C2-C4 selectivity decrease. In addition, the olefin to paraffin ratio increases.</p> <p>Fischer–Tropsch catalysts are sensitive to poisoning by sulfur-containing compounds. Cobalt-based catalysts are more sensitive than for their iron counterparts.</p> <h4><span class="mw-headline" id="Iron">Iron</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=10" title="Edit section: Iron">edit</a><span class="mw-editsection-bracket">]</span></span></h4> <p>Fischer Tropsch iron catalysts need alkali promotion to attain high activity and stability (e.g. 0.5 wt.% K2O). Addition of Cu for reduction promotion, addition of SiO2, Al2O3 for structural promotion and maybe some manganese can be applied for selectivity control (e.g. high olefinicity). The working catalyst is only obtained when – after reduction with hydrogen– in the initial period of synthesis several iron carbide phases and elemental carbon are formed whereas iron oxides are still present in addition to some metallic iron. With iron catalysts two directions of selectivity have been pursued. One direction has aimed at a low molecular weight olefinic hydrocarbon mixture to be produced in an entrained phase or fluid bed process (Sasol Synthol process). Due to the relatively high reaction temperature (approx. 340<sup>o</sup>C), the average molecular weight of the product is so low that no liquid product phase occurs under reaction conditions. The catalyst particles moving around in the reactor are small (particle diameter 100 mm) and carbon deposition on the catalyst does not disturb reactor operation. Thus a low catalyst porosity with small pore diameters as obtained from fused magnetite (plus promotors) after reduction with hydrogen is appropriate. For maximising the overall gasoline yield the olefins C<sub>3</sub>, C<sub>4</sub> have been oligomerised at Sasol. However, recovering the olefins for use as chemicals in e.g. polymerization processes is advantageous today.The second direction of iron catalyst development has aimed at highest catalyst activity to be used at low reaction temperature where most of the hydrocarbon product is in the liquid phase under reaction conditions. Typically, such catalysts are obtained through precipitation from nitrate solutions. A high content of a carrier provides mechanical strength and wide pores for easy mass transfer of the reactants in the liquid product filling the pores. The main product fraction then is a paraffin wax, which is refined to marketable wax materials at Sasol, however, also can be very selectively hydrocracked to a high quality Diesel fuel. Thus iron catalysts are very flexible.</p> <h4><span class="mw-headline" id="Ruthenium">Ruthenium</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=11" title="Edit section: Ruthenium">edit</a><span class="mw-editsection-bracket">]</span></span></h4> <p>Ruthenium is most active working at the lowest reaction temperature. It produces the highest molecular weight hydrocarbons (‘polymethylene synthesis’) Pichler and Buffleb performing thus the chain growth reaction in the cleanest mode; it acts as a Fischer Tropsch catalyst as the pure metal, without any promotors, thus providing the simplest catalytic system of Fischer Tropsch synthesis, where mechanistic conclusions should be the easiest – e.g., much easier than with iron as the catalyst. Like with nickel, the selectivity changes to mainly methane at elevated temperature. Its high price and limited world resources exclude industrial application. Systematic Fischer Tropsch studies with ruthenium catalysts should contribute substantially to the further exploration of the fundamentals of Fischer Tropsch synthesis. There is an interesting question to consider: what features have the metals nickel, iron, cobalt and ruthenium in common to let them be – and only them – Fischer Tropsch catalysts, converting the CO/H<sub>2</sub> mixture to aliphatic (long chain) hydrocarbons in a ‘one step reaction’. The term ‘one step reaction’ means that reaction intermediates are not desorbed from the catalyst surface. In particular, it is amazing that the much carbided alkalized iron catalyst gives this reaction similarly as the just metallic ruthenium catalyst. It will be seen in the next section that the kinetic principle of ‘selective inhibition’ might be the common feature which applies,in spite of differences in catalyst composition, reaction intermediates, steps of reaction and corresponding kinetic schemes. <sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span>[</span>9<span>]</span></a></sup></p> <h3><span class="mw-headline" id="LTFT_and_HTFT">LTFT and HTFT</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=12" title="Edit section: LTFT and HTFT">edit</a><span class="mw-editsection-bracket">]</span></span></h3> <p>High-temperature Fischer–Tropsch (or HTFT) is operated at temperatures of 330 ° – 350 °C and uses an iron-based catalyst.

These slurry bed and fixed-bed reactors are much larger than the sizes needed for biofuel facilities or for smaller-scale natural-gas fields. The use of microchannel reactors scales down the size of the reaction hardware and overcomes the heat and mass transport problems associated with conventional FT technology. Enhanced heat transfer inside the microchannels reactor allows for optimal temperature control, which maximizes catalyst activity and life. While no smaller scale plant is currently in commercial operation, indications show capital costs, operating costs and size could all be reduced relative to conventional FT facilities.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span>[</span>16<span>]</span></a></sup><sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span>[</span>17<span>]</span></a></sup> An order has reportedly been placed for a 1400-bbl/day modular GTL plant using the technology of a company called Velocys.<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span>[</span>18<span>]</span></a></sup></p> <p>In Australia, <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Linc_Energy" title="Linc Energy">Linc Energy</a> commenced construction in 1999 of the world's first gas–liquid plant operating on synthesis gas produced by <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Underground_coal_gasification" title="Underground coal gasification">underground coal gasification</a>.<sup id="cite_ref-Linc_19-0" class="reference"><a href="#cite_note-Linc-19"><span>[</span>19<span>]</span></a></sup> The GTL plant uses the F-T process, and produced liquids in 2008.<sup id="cite_ref-FirstUCG-GTL_20-0" class="reference"><a href="#cite_note-FirstUCG-GTL-20"><span>[</span>20<span>]</span></a></sup></p> <h3><span class="mw-headline" id="Sasol">Sasol</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20150213003247/http://en.wikipedia.org/w/index.php?title=Fischer%E2%80%93Tropsch_process&action=edit&section=15" title="Edit section: Sasol">edit</a><span class="mw-editsection-bracket">]</span></span></h3> <div class="thumb tright"> <div class="thumbinner" style="width:222px;"><a href="/web/20150213003247/http://en.wikipedia.org/wiki/File:Sasol_Garage_in_Boksburg.jpg" class="image"><img alt="" src="//web.archive.org/web/20150213003247im_/http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/Sasol_Garage_in_Boksburg.jpg/220px-Sasol_Garage_in_Boksburg.jpg" width="220" height="165" class="thumbimage" srcset="//web.archive.org/web/20150213003247im_/http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/Sasol_Garage_in_Boksburg.jpg/330px-Sasol_Garage_in_Boksburg.jpg 1.5x, //web.archive.org/web/20150213003247im_/http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/Sasol_Garage_in_Boksburg.jpg/440px-Sasol_Garage_in_Boksburg.jpg 2x" data-file-width="3648" data-file-height="2736"/></a> <div class="thumbcaption"> <div class="magnify"><a href="/web/20150213003247/http://en.wikipedia.org/wiki/File:Sasol_Garage_in_Boksburg.jpg" class="internal" title="Enlarge"></a></div> A SASOL garage in <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Gauteng" title="Gauteng">Gauteng</a></div> </div> </div> <div class="hatnote relarticle mainarticle">Main article: <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Sasol" title="Sasol">Sasol</a></div> <p>The largest scale implementation of Fischer–Tropsch technology are in a series of plants operated by <a href="/web/20150213003247/http://en.wikipedia.org/wiki/Sasol" title="Sasol">Sasol</a> in <a href="/web/20150213003247/http://en.wikipedia.org/wiki/South_Africa" title="South Africa">South Africa</a>, a country with large coal reserves, but little oil.
