  1. 1. Complete methane oxidation over alumina and zeolite supported palladium for emission control

    Författare :Ida Friberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Pd zeolite; Pd Al2O3; sulfur poisoning; stoichiometric; hydrothermal aging; water deactivation; regeneration; methane oxidation; Ba;

    Sammanfattning : The use of methane-based fuels, such as natural gas and biogas, gives lower emissions of for instance carbon dioxide (CO2) and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt methane (CH4) residuals, which are desirable to minimize since CH4 has a high global warming potential. LÄS MER

  3. 2. Gasoline Engine HCCI Combustion - Extending the high load limit

    Sammanfattning : There is an increasing global focus on reducing emissions of greenhouse gases.For the automotive industry this means reducing CO2 emissions of the vehiclesmanufactured, which is synonymous with reducing their fuel consumption oradapting them for using renewable fuels. LÄS MER

  4. 3. Characterization of domain switching and optical damage properties in ferroelectrics

    Författare :Junji Hirohashi; Fredrik Laurell; Ady Arie; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quasi-phase matching; ferroelectric domains; stoichiometric LiNbO3; stoichiometric LiTaO3; KTiOPO4; KNbO3; polarization switching; periodic electric field poling; optical damages; Optical physics; Optisk fysik;

    Sammanfattning : Nonlinear optical frequency conversion is one of the most important key techniques in order to obtain lasers with wavelengths targeted for specific applications. In order to realize efficient and tailored lasers, the quasi-phase-matching (QPM) approach using periodically-poled ferroelectric crystals is getting increasingly important. LÄS MER
