    Sammanfattning : Catalytic combustion is an environmentally benign technologywhich has recently reached the stage of commercialization.Palladium is the catalyst of choice when considering gasturbines fuelled with natural gas because of its superioractivity for methane oxidation. LÄS MER

  3. 2. Studies of partial oxidation and combustion over heterogeneous catalysis by transient experiments

    Författare :Andreas Hinz; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalytic combustion; Selective Oxidation; Sulphur dioxide; Ammonia; Methanol; Propane; Metal catalysts; Metal oxide catalysts; Transients; Simulation; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Sammanfattning : 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. LÄS MER

  4. 3. On the Function of Ceria Supported Rhodium Catalysts for Methanation of Carbon Dioxide

    Författare :Felix Hemmingsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HE-XRD; Catalytic methanation; AP-XPS; In situ spectroscopy; DRIFTS; Sabatier reaction; CO2 reduction; Hydrogenation;

    Sammanfattning : Technologies for energy harvesting of sustainable sources such as solar and wind lack an inherent energy buffer. As such, storing excess energy in chemical bonds, for example that of hydrogen (H2), is a desirable complementary concept. LÄS MER
