2. 1. CO Oxidation over Oxide Supported Platinum Catalysts

   Author : Mengqiao Di; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature activity; CO oxidation; operando spectroscopy; water promotion; active catalyst support; nitrogen oxide inhibition;

   Abstract : Catalytic oxidation of carbon monoxide (CO) is one of the most studied reactions that still needs to be improved because of its practical use in the chemical industry including feedstock purification and applications such as emission control, in-door air cleaning, improvement of fuel cell efficiency, etc. Concerning CO emissions, the transportation sector is a large contributor.

4. 2. Low temperature CO oxidation over Pt/CeO2

   Author : Noemi Bosio; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heterogeneous catalysis; Cerium oxide; CO oxidation; kinetic Monte Carlo; density functional theory;

   Abstract : The oxidation of CO to CO2 is a widely studied reaction not only for its practical applications but also for its apparent simplicity. CO oxidation is, in fact, often used as a model reaction for other oxidation reactions. READ MORE

5. 3. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

   Author : Per-Olof Larsson; Tillämpad biokemi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

   Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

6. 4. CO oxidation over platinum-ceria catalysts -- Structural dynamics and reaction mechanisms

   Author : Mengqiao Di; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO oxidation; Platinum catalysts; EXAFS; XANES; Operando spectroscopy; DRIFTS;

   Abstract : Catalytic oxidation of carbon monoxide (CO) continues to be important due to its wide applicability in emission control, in-door air cleaning, fuel cell efficiency enhancement, chemical feedstocks purification etc. The transportation sector emits most of the CO emissions. READ MORE

7. 5. Development of methane oxidation catalysts for different gas turbine combustor concepts

   Author : Sara Eriksson; Magali Boutonnet; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; catalytic combustion; methane oxidation; ceria; palladium; platinum; rhodium; TPO; Kemiteknik; Chemical engineering; Kemiteknik;

   Abstract : Due to continuously stricter regulations regarding emissions from power generation processes, development of existing gas turbine combustors is essential. A promising alternative to conventional flame combustion in gas turbines is catalytic combustion, which can result in ultra low emission levels of NOx, CO and unburned hydrocarbons. READ MORE
