2. 1. Development of a methanol reformer for fuel cell vehicles

   Author : Bård Lindström; KTH; []
   Keywords : methanol; fuel cell vehicles; reforming; catalysis; partial oxidation; steam reforming; combined reforming;

   Abstract : Vehicles powered by fuel cells are from an environmentalaspect superior to the traditional automobile using internalcombustion of gasoline. Power systems which are based upon fuelcell technology require hydrogen for operation. The ideal fuelcell vehicle would operate on pure hydrogen stored on-board. READ MORE

4. 2. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

   Author : Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

   Abstract : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.

5. 3. Techno-economic analysis of combined cycle power plants integrated with chemical looping reforming and CO2 capture

   Author : Shareq Mohd Nazir; Olav Bolland; Shahriar Amini; Norway Trondheim Norwegian University of Science and Technology Department of Energy and Process Engineering; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Abstract : The current thesis is a part of the EU FP7 Project titled NanoSim. It focuses on techno-economic analysis of combined cycle power plants with integrated pre-combustion CO2 capture and reforming of Natural Gas (NG). READ MORE

6. 4. Catalytic Conversion of Undesired Organic Compounds to Syngas in Biomass Gasification and Pyrolysis Applications

   Author : Pouya H. Moud; Klas Engvall; Klas J. Andersson; Roberto Lanza; Mats Ahmadi Götelid; Anker Degn Jensen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tar reforming; biomass gasification; Ni-based catalyst; potassium; sulfur; pyrolysis gas; bio-crude conditioning; gas conditioning; Fe-based catalyst; tjärreformering; biomassaförgasning; Ni-baserad katalysator; kalium; svavel; pyrolysgas; konditionering bio-råolja; gaskonditionering; Fe-baserad katalysator; Chemical Engineering; Kemiteknik;

   Abstract : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. READ MORE

7. 5. Syngas production by integrating thermal conversion processes in an existing biorefinery

   Author : Katarina Åberg; Anders Nordin; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

   Abstract : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. READ MORE
