    Sammanfattning : 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. LÄS MER

  7. 5. Zeolite ZSM5 catalysts for abatement of nitrogen oxide

    Författare :Bager Ganemi; KTH; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
