6. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles
Sammanfattning : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. LÄS MER
7. Kinetic modeling of autothermal reforming of heptane for a fuel cell - auxiliary power unit
Sammanfattning : AbstractThe transport sector contributes significantly to the increasing amounts of air pollution. The pollution from idling heavy duty vehicles can be reduced by using a fuel cell auxiliary power unit (FC-APU) that supplies the vehicle with electricity. This licentiate thesis deals with production of hydrogen, which feeds the fuel cell. LÄS MER
8. Hydrogen production from fossil fuels with carbon dioxide capture, using chemical-looping technologies
Sammanfattning : Carbon capture and storage have been receiving increasing interest lately, mainly as an option to reduce CO2 emissions from the power sector. The concept could be adapted for production of H2 as well, which would provide a carbon free energy carrier that could be used for example as transportation fuel. LÄS MER
9. Strategies for controlling solid biomass conversion in dual fluidized bed gasifiers
Sammanfattning : In the chemical industry, Synthesis Gas (syngas) has been traditionally produced by steam reforming of natural gas and naphtha. Steam gasification of biomass offers an alternative route for the production of syngas from renewable sources. LÄS MER
10. Operational strategies to control the gas composition in dual fluidized bed biomass gasifiers
Sammanfattning : Steam gasification of biomass can increase the share of renewable energy and material resources in the energy sector, transportation and different industries. Prior its application, the raw gas produced in biomass gasifiers needs to be cleaned from impurities. LÄS MER
