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

    Author : Per-Olof Larsson; Tillämpad biokemi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

    Author : Magali Ferrandon; KTH; []
    Keywords : wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

    Abstract : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. READ MORE

  4. 4. Selective oxidation over mixed oxide catalysts

    Author : Robert Häggblad; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propane; catalysis; Selective oxidation; transition metal oxides; vanadium; molybdenum; methanol oxidation; ammoxidation; propene; acrylonitrile; formaldehyde;

    Abstract : Since the metal oxide catalysts used in many chemical processes show very high selectivity for the products aimed at, both today and in the future, they play a key role in the environmentally and economically sustainable production of chemical intermediates. Two processes of this sort have been studied in the thesis: the ammoxidation of propane and propene over a Mo-V-Nb-Te-oxide catalyst and the selective oxidation of methanol over vanadium-based catalysts.
