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

    University dissertation from Stockholm : Kemiteknik

    Author : Bård Lindström; KTH.; [2003]
    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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Chunguang Zhou; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energiteknik; Energy Technology; 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.

    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

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

    University dissertation from Umeå : Umeå Universitet

    Author : Katarina Åberg; Umeå universitet.; [2014]
    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

  5. 5. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

    University dissertation from Department of Heat and Power Engineering, Lund university
