  2. 11. 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

  4. 12. Organic Reactions i Organised Media

    Author : TOMASZ WITULA; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; mesoporous material; microemulsion; silica; lipase; Liquid crystal; alumina; entrapment.; heterogenized; titania; organic synthesis;

    Abstract : A common problem in synthetic organic chemistry is reactant incompatibility between lipophilic organic compounds and inorganic salts. The thesis reports an investigation of some organic reactions, involving incompatible substrate and nucleophile, performed in liquid crystalline phases and also in slurries of mesoporous materials with different symmetry.

  5. 13. Mesoporous Titania for High Rate Electrochemical Energy Storage

    Author : Giulio Calcagno; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous Titanium Dioxide; XAS; Pseudocapacitance; Hybrid Asymmetric Supercapacitors;

    Abstract : Mesoporous titanium oxides are increasingly attracting interest as potential candidates for fast electrochemical energy storage. In this thesis, mesoporous titania of different polymorphs have been evaluated in relation to their ability to reversibly store Li+ ions inside their structure. READ MORE

  7. 15. Hybrid nano titania: molecular formation mechanisms and applications in nanotechnology

    Author : Fredric Svensson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanomaterials are defined as materials with one dimension smaller than 100 nm. At this size, exotic properties start to emerge, making them interesting for a wide range of applications including catalysis, electronics, theranostics, and “smart materials”. READ MORE
