  4. 2. Catalytic Emission Abatement and Gas Separation

    Author : Martin Petersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx reduction; Ozone promotion; Flow reactor studies; Propane oxidation; Molecular simulations; Sulfur dioxide promotion; Zeolite adsorption; Environmental heterogeneous catalysis; Mean-field kinetic modeling; CO oxidation;

    Abstract : Air pollution is still today a major health problem. Emissions from mobile and stationary sources are regulated, but economical considerations limit the implementation of the most efficient abatement systems. To improve urban air quality, there is therefore a need to develop simple, durable and cost efficient emission control methods. READ MORE

  5. 3. Fundamental studies of catalytic systems for diesel emission control

    Author : Xavier Auvray; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NH3 SCR; NO oxidation; sulfur; hysteresis; kinetic modeling; SpaciMS; catalyst acidity; DOC; aging; Pt Al2O3;

    Abstract : Due to global lean exhaust gas and new emission regulations, exhaust aftertreatment systems of diesel engines are more and more sophisticated and composed of a series of catalytic units. In the present work, two of these catalytic systems were studied with different approach. READ MORE

  6. 4. Complete methane oxidation over alumina and zeolite supported palladium for emission control

    Abstract : The use of methane-based fuels, such as natural gas and biogas, gives lower emissions of for instance carbon dioxide (CO2) and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt methane (CH4) residuals, which are desirable to minimize since CH4 has a high global warming potential. READ MORE
