  2. 1. Electrooxidation of glycerol and methanol on gold

    Author : Mikael Valter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; van der Waals; electrochemistry; methanol; gold; glycerol; DFT;

    Abstract : Burning of fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy. READ MORE

  4. 2. Numerical Studies of Methanol PPC Engines and Diesel Sprays

    Author : Mateusz Pucilowski; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Partially Premixed Combustion PPC ; spray-wall interaction; piston geometry; multiple injections; ICE; ignition front; diffusion flame; combustion mode; RANS; LES; PPC; Diesel spray;

    Abstract : The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). READ MORE

  5. 3. 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

  6. 4. 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

  7. 5. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion

    Author : Senthil Krishnan Mahendar; Anders Christiansen Erlandsson; Christer Spiegelberg; James Szybist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; Methanol; Dilution; Spark Ignition; Miller Timing; Machine Design; Maskinkonstruktion;

    Abstract : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. READ MORE
