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

    Author : Magnus Walander; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; effective diffusivity; EATS; synthetic catalyst activity test; scanning electron microscope; washcoat; diesel oxidation catalyst; Exhaust aftertreatment modelling; gravimetric analysis;

    Abstract : 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. READ MORE

  3. 3. Deactivation of diesel oxidation catalysts

    Author : Jonas Andersson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated aging: Diesel exhaust: Oxidation catalyst: Sulfur deactivation: Phosphorous poisoning: CO oxidation: Pt dispersion: Al2O3: Sintering: TEM: XPS;

    Abstract : 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. READ MORE
