  4. 23. Studies on Lean NOx Reduction with Ammonia. Catalysts and Sensors

    Författare :Mikaela Wallin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; catalysis; Pt SiO2; NOx reduction; gas sensor; DFT; SCR; H-ZSM-5; in situ FTIR; LCAO; DRIFT; high throughput screening; transient ammonia supply; ammonia; microemulsion; perovskite;

    Sammanfattning : Selective catalytic reduction of NOx with ammonia, NH3-SCR, is a promising technique to reduce NOx under lean conditions, e.g. in diesel engine exhausts. The main objective of this thesis was to gain further understanding of key parameters affecting the performance of catalysts and sensors for NH3-SCR. LÄS MER

  7. 25. Organic Reactions i Organised Media

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

    Sammanfattning : 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.
