  1. 21. Nanotemplated High-Temperature Materials for Catalytic Combustion

    Författare :Erik Elm Svensson; Sven Järås; Magali Boutonnet; James J. Spivey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon templating; Catalytic combustion; Ceria; Gas turbine; Hexaaluminate; Magnesia; Methane; Microemulsion; Perovskite; Chemical engineering; Kemiteknik;

    Sammanfattning : Catalytic combustion is a promising technology for heat and power applications, especially gas turbines. By using catalytic combustion ultra low emissions of nitrogen oxides (NOX), carbon monoxide (CO) and unburned hydrocarbons (UHC) can be reached simultaneously, which is very difficult with conventional combustion technologies.
