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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Study of Catalyst Deactivation in Three Different Industrial Processes

    Författare :Ann-Charlotte Larsson; Mehri Sanati; Ferruccio Trifiro; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deactivation; catalyst; SCR; VOC; steam reforming; aerosol particle; potassium; zinc; ash salts; biomass; organosilicon; Chemical engineering; Kemiteknik; Kemi; Chemistry;

    Sammanfattning : Deactivation of catalysts were investigated focusing on three industrial processes: 1) Selective Catalytic Reduction (SCR) for abatement of NOx from biomass combustion using V2O5-WO3 /TiO2 catalysts; 2) Catalytic oxidation of volatile organic compounds (VOC) from printing industries using a Pt/γ-Al2O3 catalyst; and 3) Ni and Pt/Rh catalysts used in steam reforming reaction of bio-syngas obtained from biomass gasification.The aim has been to simulate industrial conditions in laboratory experiments in order to comprehend influence of compounds affecting catalysts performance.
