  2. 1. Transport in Oxides Studied by Gas Phase Analysis

    Author : Qian Dong; Gunnar Hultquist; W.J. Quadakkers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas Phase Analysis; metal; oxide; platinum; vitreous silica; yttria stabilized zirconia; diatomic gas; oxidation; dissociation; permeation; uptake release.; Chemical engineering; Kemiteknik;

    Abstract : The transport in oxides is studied by the use of gas phase analysis (GPA). An experimental method to identify transported species of gases and their contribution to the overall transport of gases in oxides and an experimental method to evaluate the parameters diffusivity, concentration, permeability of gases in oxides and effective pore size in oxides are developed, respectively.

    Keywords : planar laser-induced fluoresence; degenerate four wave mixing; gas phase; CO oxidation; model catalyst; hetergeneous catalysis; laser-diagnostiska tekniker; gasfasdetektering; modellkatalys; heterogen katalys;

    Abstract : This thesis deals with the development and application of laser-based techniques, for gas phasecharacterization/gas imaging in heterogeneous catalysis. Two techniques are presented: planar laser-induced fluorescence (PLIF) and degenerate four wave mixing (DFWM). READ MORE

  6. 4. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

    Author : Jakob Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOx; absorption; ClO2; sulfite oxidation; gas-phase oxidation; NOx; Emissions control; scale-up;

    Abstract : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. READ MORE

  7. 5. In situ structural studies and gas phase visualization of model catalysts at work

    Author : Sara Blomberg; Synkrotronljusfysik; []
    Keywords : CO-oxidation; model catalysts; AP-XPS; PLIF; Pd; Rh; PdAg; Fysicumarkivet A:2017:Blomberg;

    Abstract : This thesis reports on in situ structural studies relevant to a catalytic surface during CO oxidation. The materials that have been studied are palladium, rhodium and an alloy of palladium and silver, with applications in emission cleaning by catalytic converters in vehicles. READ MORE
