  3. 2. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

    Författare :Per-Olof Larsson; Tillämpad biokemi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

    Sammanfattning : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. LÄS MER

    Sammanfattning : This thesis presents experimental studies of three different chemical reaction steps relevant for heterogeneous catalysis: dissociation, desorption, and oxidation. CO on single-crystal metal surfaces was chosen as the model systems. LÄS MER

  5. 4. CO Oxidation over Oxide Supported Platinum Catalysts

    Författare :Mengqiao Di; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature activity; CO oxidation; operando spectroscopy; water promotion; active catalyst support; nitrogen oxide inhibition;

    Sammanfattning : Catalytic oxidation of carbon monoxide (CO) is one of the most studied reactions that still needs to be improved because of its practical use in the chemical industry including feedstock purification and applications such as emission control, in-door air cleaning, improvement of fuel cell efficiency, etc. Concerning CO emissions, the transportation sector is a large contributor.

  7. 5. Catalytic Emission Abatement and Gas Separation

    Författare :Martin Petersson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
