  1. 1. Tuned acidity in zeotypes: A descriptor to unravel the direct conversion of methane to methanol?

    Author : Simone Creci; Chalmers University of Technology; []
    Keywords : methane; methanol; zeotype; catalysis; MFI; zeolite; infrared spectroscopy;

    Abstract : The catalyst's acidity is crucial in countless chemical reactions, and thus to tune this parameter means to take the lead on the desired catalytic reaction. Therefore, it is not surprising that zeolites have been used since decades as catalysts for their outstanding properties of solid acids. READ MORE

  2. 2. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

    Author : Johan Agrell; KTH; []
    Keywords : PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

    Abstract : 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. READ MORE

  3. 3. 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. 4. CO2 activation for methanol synthesis on copper and indium oxide surfaces

    Author : Alvaro Posada Borbon; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Methanol conversion; Heterogeneous catalysis; Density functional theory; Copper surface; Indium oxide​​; CO2 reduction;

    Abstract : Catalytic recycling of CO2 to added-value chemicals, such as methanol (CH3OH), has been proposed as a possible way for sustainable production of fuel and chemicals, in addition to providing a route to mitigate climate change. Multiple systems are known to be active for the conversion of CO2 to methanol, and the state of the art catalyst is Cu/ZnO/Al2O3. READ MORE

  5. 5. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Author : Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Abstract : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. READ MORE
