2. 1. Unfolding the formative phase of gasified biomass in the European Union: The role of system builders in realising the potential of second-generation transportation fuels from biomass

   Author : Hans Hellsmark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technical change; second-generation transportation fuels; technology policy.; technological innovation systems; biomass gasification; system builders;

   Abstract : In an era of climate change, the process of and time frame for fostering new industries with the capacity of being innovative and able to diffuse a wide range of renewable energy technologies on a large scale has become a pressing issue. In the midst of the creation of such industries are the system builders―without such actors, new technologies and industries would not emerge. READ MORE

4. 2. Development of integrated cellulose- and starch-based ethanol production and process design for improved xylose conversion

   Author : Borbala Erdei; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; wheat straw; wheat; first-generation ethanol; second-generation; integrated process; SSF; simultaneous saccharification and co-fermentation; xylose fermentation; S. cerevisiae TMB3400;

   Abstract : Transportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of second-generation bioethanol from lignocellulose (2G).

5. 3. Life Cycle Assessment of Present and Future Marine Fuels

   Author : Selma Bengtsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   Abstract : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

6. 4. Catalytic conversion of biomass-derived synthesis gas to liquid fuels

   Author : Rodrigo Suárez París; Magali Boutonnet; Agustín Martínez Feliu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; Fischer-Tropsch wax; higher alcohols; hydroconversion; kinetic modelling; methanol cofeeding; microemulsion; MoS2; noble metal; syngas; Chemical Engineering; Kemiteknik;

   Abstract : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. READ MORE

7. 5. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

   Author : Cristhian Carrasco; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

   Abstract : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. READ MORE
