  1. 1. Selective oxidation over mixed oxide catalysts

    Author : Robert Häggblad; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propane; catalysis; Selective oxidation; transition metal oxides; vanadium; molybdenum; methanol oxidation; ammoxidation; propene; acrylonitrile; formaldehyde;

    Abstract : Popular Abstract in Swedish En spännande utmaning för forskare inom både akademin och industrin är att utveckla industriella processer som mer effektivt använder både befintliga som alternativa råvaror för produktion av viktiga kemiska intermediat. Sådana intermediat används i sin tur som råvara för att framställa funktionella och idag ovärderliga material såsom plaster, fibrer, gummin, färger, ytbehandlingsmedel m. READ MORE

  2. 2. A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

    Abstract : Transient experiments are one of many techniques available to study heterogeneous catalysis and the catalysts used. The results obtained by transient experiments contain valuable information that is helpful in explaining reaction mechanism and interaction at the catalytic surface. READ MORE

  4. 4. Catalytic Emission Abatement and Gas Separation

    University dissertation from Secretary, Dept. of Chem. Eng. II, P.O. Box 124, SE-22100 Lund

    Author : Martin Petersson; [2006]
    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

    Abstract : The proton exchange membrane fuel cell generates electricity from hydrogen and oxygen (from air) through electrocatalytic reactions in an electrochemical cell. The Pt/C catalyst, commonly used in PEM fuel cells, is very sensitive to impurities that can interact with the active catalyst sites and limit fuel cell performance. READ MORE
