    Abstract : This licentiate thesis is a summary of my study on thermal deactivated commercial threeway catalysts (TWCs). The experiments were performed using gasoline and a E85 fuelmixture of 85 vol.% ethanol and 15 vol.% gasoline. READ MORE

  4. 4. Zeolite ZSM5 catalysts for abatement of nitrogen oxide

    Author : Bager Ganemi; KTH; []
    Keywords : ;

    Abstract : Airborne pollutants from the combustion of fossil fuels area global problem. Emission of nitrogen oxides (NOx) is increasing with the worldwide increase in theuse of energy. Atmospheric and photochemical reactions linknitrogen oxides to hydrocarbons and tropospheric ozone. READ MORE

  5. 5. Preparation of New Catalytic Materials by Small Particle Technology

    Author : Anders Törncrona; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : New techniques for preparation of catalytic materials with novel properties are presented in this thesis. Three new catalytic materials; washcoated fibres, highly dispersed metal oxides on titania coated silica particles and discrete colloidal ZSM-5 crystals with a low SiO2/Al2O3 ratio have been prepared and characterised.
