  2. 1. Hydrogen generation from dimethyl ether by autothermal reforming

    Author : Marita Nilsson; Lars Pettersson; Ann Cornell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; dimethyl ether; fuel cell; hydrogen; palladium; reforming catalyst; temperature-programmed reduction; truck idling; X-ray diffraction; zinc; Chemical engineering; Kemiteknik;

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE

  4. 2. RhPt and Ni based catalysts for fuel reforming in energy conversion

    Author : Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

    Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE

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

    Author : Xanthias Karatzas; Lars J. Pettersson; James Spivey; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Kinetic modeling of autothermal reforming of heptane for a fuel cell - auxiliary power unit

    Author : Mattias Modén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heptane; Keywords: Steam reforming; Kinetic modeling; Oxidation; Autothermal reforming; FC-APU;

    Abstract : 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. READ MORE

  7. 5. Hydrogen Generation for Fuel Cells in Auxiliary Power Systems

    Author : Marita Nilsson; Lars J. Pettersson; Gunther Kolb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; diesel; dimethyl ether; fuel cell; fuel-flexible reformer; hydrogen; PdZn alloy; reforming catalyst; reformer design; Rh; Chemical engineering; Kemiteknik;

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE
