  2. 16. Nanotemplated High-Temperature Materials for Catalytic Combustion

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

    Abstract : 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.

  4. 17. Bimetallic palladium catalysts for catalytic combustion of methane

    Author : Katarina Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; catalytic combustion; gas turbine; methane; palladium; bimetal; morphology; TPO; TEM; EDS; methane activity; stability; pressure; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : Catalytic combustion is a promising combustion technique in gas turbines, which results in ultra low levels of NOx, CO and unburned hydrocarbons. Due to the low combustion temperature achieved in catalytic combustion almost no thermal NOx is formed. The focus in this thesis will be on the first stage in a catalytic combustion chamber, i.e. READ MORE

  5. 18. On Catalytic Mechanisms for Rational Enzyme Design Strategies

    Author : Charlotte Kürten; Per-Olof Syrén; Rudolf Allemann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; catalytic mechanisms; terpene cyclase; triterpene cyclase; solvent dynamics; protein hydration; thermodynamics; quantum tunneling; polycyclization; natural compounds; ? ?-hydrolase; esterase; amidase; enzyme engineering; biocatalysis; Bioteknologi; Biotechnology;

    Abstract : Enzymes enable life by promoting chemical reactions that govern the metabolism of all living organisms. As green catalysts, they have been extensively used in industry. However, to reach their full potential, engineering is often required, which can benefit from a detailed understanding of the underlying reaction mechanism. READ MORE

  7. 20. A Study of Catalytic Ignition and Kinetic Phase Transitions

    Author : Mats Rinnemo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalytic ignition; catalysis; kinetic phase transitions; platinum;

    Abstract : Catalytic ignition and kinetic phase transitions are two critical phenomena which can occur in heterogeneously catalyzed reaction systems. They have in common that the system behavior changes qualitatively when a control parame-ter passes through a critical value. READ MORE
