  2. 6. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments

    Author : Louise Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NO oxidation; Monte Carlo simulations; platinum oxide; kinetic modelling; NOx storage; barium oxide; environmental catalysis; NOx removal; platinum; flow reactor measurements;

    Abstract : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. READ MORE

  4. 7. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor

    Author : Erik Ahlberg; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Secondary organic aerosols; oxidation flow reactor; volatile organic compounds; climate;

    Abstract : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. READ MORE

  5. 8. Studies of Supported Catalysts for Environmental Applications: - Flow Reactor Measurements, Monte Carlo Simulations and High Throughput Screening

    Author : Peter Thormählen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalytic oxidation of carbon monoxide; supported heterogeneous catalysts; flow reactor measurements; high throughput screening; low temperature catalytic activity; cobalt oxide; platinum; temperature programmed methods; Monte Carlo simulations; environmental catalysis;

    Abstract : The use of heterogeneous catalysts for environmental applications, primarily for reduction of harmful emissions from vehicles and stationary sources, has successively increased during the last three decades. Driven by emission regulations, research and development within this area attract large interest and resources, especially for automotive applications. READ MORE
