  5. 3. Studies of Catalytic Low-Temperature CO Oxidation over Cobalt Oxide and Related Transition Metal Oxides

    Author : Jonas Jansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalytic CO oxidation; in-situ XRD; transition metal oxides; low temperature activity; kinetic modelling; in-situ FTIR; in-situ XANES; cobalt oxide; catalyst deactivation; reaction mechanism;

    Abstract : The catalytic oxidation of carbon monoxide at low temperatures is important in many applications. The use of a low temperature active catalyst may lower the emissions during the cold-start of a car, and volatile organic compounds in exhaust gases from stationary sources might be treated without the need of preheating the gas.

  6. 4. Low-Temperature Oxidation of CO and Volatile Organic Compounds over Supported Platinum Catalysts

    Author : Karl Arnby; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hexamethyldisiloxane; alumina; catalytic deactivation; environmental catalysis; platinum; volatile organic compounds; carbon monoxide; low-temperature activity;

    Abstract : The catalytic oxidation of carbon monoxide (CO) and volatile organic compounds (VOC) is important for the reduction of harmful emissions from both vehicles and from stationary sources. Both these applications suffer from poor catalytic efficiency at lower temperatures. READ MORE

  7. 5. Nanomaterials for high-temperature catalytic combustion

    Author : Erik Elm Svensson; Sven Järås; Magali Boutonnet; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; catalytic combustion; microemulsion; hexaaluminate; magnesia; perovskite; ceria; methane; gas turbine; katalytisk förbränning; mikroemulsion; hexaaluminat; magnesia; perovskit; ceriumdioxid; metan; gasturbin; Catalysis; Katalys;

    Abstract : Katalytisk förbränning är en lovande teknik för användning vid kraftgenerering, särskilt för gasturbiner. Genom att använda katalytisk förbränning kan man nå mycket låga emissioner av kväveoxider (NOX), kolmonoxid (CO) och oförbrända kolväten (UHC) samtidigt, vilket är svårt vid konventionell förbränning.
