  1. 1. Modelling of Catalytic Monolith Reactors for Exhaust Aftertreatment

    Författare :Magnus Walander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel oxidation catalyst; effective diffusivity; washcoat; EATS; gravimetric analysis; parameter estimation; synthetic catalyst activity test; Exhaust aftertreatment modelling; scanning electron microscope;

    Sammanfattning : The incomplete combustion of liquid or gaseous fuels in the internal combustion engine inherently produces several toxic emissions that need to be  removed. This is done through a series of catalytic converters, referred to as the exhaust aftertreatment system (EATS), each catalyst with its own purpose. LÄS MER

  3. 2. TOWARDS VALIDATED CATALYTIC REACTOR MODELS

  4. 3. Deactivation of diesel oxidation catalysts

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated aging: Diesel exhaust: Oxidation catalyst: Sulfur deactivation: Phosphorous poisoning: CO oxidation: Pt dispersion: Al2O3: Sintering: TEM: XPS;

    Sammanfattning : To meet the demand for heavy- and light-duty diesel vehicles on expansive markets while complying with current and future emission standards, it is necessary to reinsure the long-livety of the applied exhaust aftertreatment technology. Loss of catalytic performance may be associated with environmental as well as economical consequences. LÄS MER
