  2. 1. Self-adaptable catalysts : Importance of flexibility and applications in asymmetric catalysis

    Author : Ester Fjellander; Christina Moberg; Jay Siegel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptable; flexible; semi-flexible; symmetry; conformational study; mechanistic study; rotation barrier; VT NMR; asymmetric catalysis; ligand design; allylic alkylation; hydrogenation; azepines; dioxaphosphepines; phosphepines; amines; phosphines; phosphoramidites; phosphinites; palladium; rhodium; Organic chemistry; Organisk kemi;

    Abstract : The topic of this thesis is the design and synthesis of biaryl-based self adaptableligands for asymmetric metal catalysis. The results discussed in papers I-III are covered, together with some unpublished results concerning substrate-adaptable catalysts. A general survey of self-adaptable catalysts is presented first.

  4. 2. Coke on Supported Palladium and Platinum Catalysts

    Author : Mikael Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TPO; palladium; deactivation; coke; propane dehydrogenation; microbalance; vegetable oil hydrogenation; acetylene hydrogenation; catalysis; platinum;

    Abstract : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. READ MORE

  5. 3. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

    Author : Magali Ferrandon; KTH; []
    Keywords : wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

    Abstract : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. READ MORE

  6. 4. 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

  7. 5. Bimetallic Palladium Catalysts for Methane Combustion in Gas Turbines

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

    Abstract : Catalytic combustion is a promising combustion technology for gas turbines, which results in ultra low emission levels of nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbons (UHC). Due to the low temperature achieved in catalytic combustion almost no thermal NOx is formed. READ MORE
