Groeneveld/Van Swaaij. </p><p class="normal">The work on <b>biomass</b> shifted in the years 2007 – 2014 from only biofuels to a mix of <b>biofuels</b> (refinery feeds & blending compounds) and <b>biochemicals</b>. A research line on <b>biomaterials</b> (thermoplastics) is being started-up. The work on biochemicals is moving in the directions of smart combination & integration of conversion and separation and also includes the exploration of the interface between biotechnology and thermochemistry (e.g. production and purification of fermentable sugars via pyrolysis of lignocelluloses). </p><p class="normal">In 2012 J.P. Lange (Shell) joint the group; he brings in knowledge on the chemistry and catalysis of biomass conversions. The work on biochemicals clearly showed the need to include more research on <b>separations</b> in our portfolio. Separation of sugars from lignin derivatives, algae lipid extraction using switchable solvents, and the recovery of volatile fatty acids from diluted aqueous streams are our current research lines in the bio-domain. </p><p class="normal">We further expanded our work on separations to the development of <b>affinity separations</b> for close boiling systems aiming at reducing the (energetic) cost of these processes. A.A. Kiss (Akzo Nobel) joined the team at the end of 2014 to support our work on separations. The groups work on <b>CCS</b> has progressed into the broader theme of <b>recovery and recycling of key elements. </b>Here we study: i) CO<sub>2</sub> air capture, ii) processes utilizing CO<sub>2</sub> and electricity as feedstock (products: algae, MEOH), iii) recovery of P & N from waste streams. For smaller scale MEOH production a dead-end reactor with internal recycle is under development. </p><p class="normal">Our <b>water</b> research is closely related to our bio-refinery work as we investigate the conversion of bio-based aqueous waste streams to H<sub>2</sub>/CH<sub>4</sub>. Also, a new process to separate salts from water (e.g. for the production of drinking water) based on supercritical conditions is being developed. </p></main><footer class="footer "><div class="footer__prefooter"><div class="footer__prefooter-container"><div class="footer__addressblock"><div class="footer__address"><span dir="ltr">University of Twente</span><br/><span dir="ltr">Drienerlolaan 5</span><br/><span dir="ltr">7522 NB Enschede</span><br/></div><div class="footer__contact"><span dir="ltr">0031 53 489 9111</span><br /><a href="mailto:info@utwente.nl">info@utwente.nl</a><br /><a href="http://www.utwente.nl/en/contact/">Route</a></div></div><div class="footer__image " style="background-image: url('/.wh/ea/uc/i42e232e60102843683006edab402addbd7d751c0b1230301c005/meander.avif'); "><div class="footer__icon UT-icon-UT_icon_16_pointer-24px themecolor--bg"></div></div></div></div><div class="footer__footer"><div class="footer__footerlinks"><a class="footer__footerlink" href="https://www.utwente.nl/en/about-our-website/disclaimer/" dir="ltr">Disclaimer & Copyright</a><a class="footer__footerlink" href="https://www.utwente.nl/en/about-our-website/" dir="ltr">Privacy & Cookies</a><span class="footer__footerlink" dir="ltr">Last Update 20/09/2024</span><div class="footer__logo"><a class="footer__logo__ut" href="https://www.utwente.nl/en/" aria-label="University of Twente homepage"><img src="/.publisher/sd/utwente_base/ws2016/img/logos/ut-logo-white-en.svg" alt="University of Twente." /></a></div></div></div></footer><div class="searchsheet searchsheet--init searchsheet--showquicklinks"><div class="searchsheet__content searchsheet__content--init"><div class="searchsheet__header"><form class="searchsheet__searchform" method="get" onsubmit="return false;" role="search"><span class="searchsheet__searchicon"></span><input name="q" class="searchsheet__searchfield" type="text" aria-label="Search in site" placeholder="Search" autocapitalize="off" autocomplete="off" /><a href="#" class="searchsheet__searchfield-clear UT-icon-UT_icon_47_cross-16px" aria-label="Clear site search"></a></form><a href="#" class="searchsheet__close"><span class="searchsheet__close-label">Close</span><span class="searchsheet__close-icon UT-icon-UT_icon_47_cross-16px"></span></a></div><div class="searchsheet__container"><div class="searchsheet__quickresults"><div class="searchsheet__section"><span class="searchsheet__section-title">Suggestions</span><div class="searchsheet__section-links searchsheet__suggestions"></div></div></div><div class="searchsheet__results"><div class="searchsheet__tabs"><div class="searchsheet__tabscontainer"></div></div><div class="searchsheet__status"></div><div class="searsia__results"></div></div></div></div></div></div><div class="theme__docstate"><span class="theme__docstate-cta"></span><span class="theme__docstate-cta-hover"></span><span class="theme__docstate-state"></span></div></body></html>
