  3. 2. Catalytic combustion of gasified waste

    Författare :Henrik Kusar; KTH; []
    Nyckelord :Catalytic combustion; Gasified waste; LHV-fuel; RDF; Biomass; Selective catalytic oxidation; NH3; NOX; Palladium; Platinum; Hexaaluminate; Garnet; Spinel; Deactivation; Sulphur; Poisoning;

    Sammanfattning : This thesis concerns catalytic combustion for gas turbineapplication using a low heating-value (LHV) gas, derived fromgasified waste. The main research in catalytic combustionfocuses on methane as fuel, but an increasing interest isdirected towards catalytic combustion of LHV fuels. LÄS MER

  4. 3. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

    Författare :Göran Olofsson; Kemiska institutionen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

    Sammanfattning : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. LÄS MER

  5. 4. 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

  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
