1. 6. From torrefaction to gasification : Pilot scale studies for upgrading of biomass

   Författare :Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

   Sammanfattning : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

3. 7. Rhodium diesel-reforming catalysts for fuel cell applications

   Författare :Xanthias Karatzas; Lars J. Pettersson; James Spivey; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autothermal reforming; auxiliary power unit; BET; chemisorption; diesel; fuel cell; hydrogen; monolith; reforming catalyst; reformer design; Rh; RhPt alloy; TEM; TPO; TPR; XRD; XPS; zone coating; Chemical engineering; Kemiteknik;

   Sammanfattning : Heavy-duty diesel truck engines are routinely idled at standstill to provide cab heating or air conditioning, and in addition to supply electricity to comfort units such as radio and TV. Idling is an inefficient and unfavorable process resulting in increased fuel consumption, increased emissions, shortened engine life, impaired driver rest and health, and elevated noise. LÄS MER

   Sammanfattning : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.
