   Author : Philippe Thevenin; KTH; []
   Keywords : catalytic combustion; gas turbine; methane; palladium; alumina; barium; lanthanum; oxidation; preparation; temperature-programmed oxidation TPO ; decomposition; reoxidation; X-ray photoelectron spectroscopy XPS ; metal-support interaction; deactiva;

   Abstract : Catalytic combustion is an environmentally benign technologywhich has recently reached the stage of commercialization.Palladium is the catalyst of choice when considering gasturbines fuelled with natural gas because of its superioractivity for methane oxidation. READ MORE

4. 2. 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. 3. Materials for High-Temperature Catalytic Combustion

   Author : Anders Ersson; KTH; []
   Keywords : catalytic combustion; catalyst materials; palladium; platinum; bimetallic; garnet; spinel; hexaaluminate; deactivation; sulphur; poisoning; diesel; methane; hydrocarbons;

   Abstract : Catalytic combustion is an environmentally friendlytechnique to combust fuels in e.g. gas turbines. Introducing acatalyst into the combustion chamber of a gas turbine allowscombustion outside the normal flammability limits. READ MORE

6. 4. 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.

7. 5. 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.
