  1. 1. Exhaust aftertreatment under lean conditions, regenerable SOx traps and NOx reduction catalysts

    Author : Lisa Kylhammar; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogenous catalysis; Selective catalytic reduction; HC-SCR; Sulfur storage; SOx trap; Spectroscopy; Lean exhausts; NOx; Ag Al2O3; DRIFT; XPS;

    Abstract : The aim of this thesis was to investigate i) potential materials for regenerable SOx traps and ii) the influence of silver distribution within Ag/Al2O3 catalysts on the selective reduction of NOx by hydrocarbons (HC-SCR). Both areas are highly relevant for present and future vehicle aftertreatment technologies for lean exhausts. READ MORE

  3. 3. Advances in Stereoselective Palladium(ΙΙ)-Catalyzed Oxidative Transformations of Allenes

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Daniels Posevins; Jan-Erling Bäckvall; Troels Skrydstrup; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synthesis; Palladium Catalysis; Allenes; Biomimetic; Carbocyclization; Borylation; Carbonylation; Oxidation; Heterogeneous; Organic Chemistry; organisk kemi;

    Abstract : Palladium(ΙΙ)-catalyzed carbon-carbon and carbon-heteroatom bond formation via selective C-H bond oxidation constitutes a step-economical and versatile approach towards complex target molecules. This thesis has been focused on the development of new selective palladium(ΙΙ)-catalyzed transformations of allenes under oxidative conditions catalyzed by either homogenous or heterogeneous palladium(ΙΙ) catalysts.
