  1. 1. Exploring Novel Catalytic Chalcogenide Antioxidants

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Johansson; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; catalytic; toxicity; ROS; neutrophil; glutathione peroxidase mimic; macrophage.; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. READ MORE

  2. 2. Catalytic combustion of gasified waste

    University dissertation from Stockholm : Kemiteknik

    Author : Henrik Kusar; KTH.; [2003]
    Keywords : Catalytic combustion; Gasified waste; LHV-fuel; RDF; Biomass; Selective catalytic oxidation; NH3; NOX; Palladium; Platinum; Hexaaluminate; Garnet; Spinel; Deactivation; Sulphur; Poisoning;

    Abstract : This thesis concerns catalytic combustion for gas turbineapplication using a low heating-value (LHV) gas, derived fromgasified waste. The main research in catalytic combustionfocuses on methane as fuel, but an increasing interest isdirected towards catalytic combustion of LHV fuels. READ MORE

  3. 3. Catalytic combustion of methane

    University dissertation from Stockholm : Kemiteknik

    Author : Philippe Thevenin; KTH.; [2002]
    Keywords : catalytic combustion; gas turbine; methane; palladium; alumina; barium; lanthanum; oxidation; preparation; temperature-programmed oxidation TPO ; decomposition; reoxidation; X-ray photoelectron spectroscopy XPS ; metal-support interaction; deactiva;

    Abstract : Catalytic combustion is an environmentally benign technologywhich has recently reached the stage of commercialization.Palladium is the catalyst of choice when considering gasturbines fuelled with natural gas because of its superioractivity for methane oxidation. READ MORE

  4. 4. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Klas Källström; Uppsala universitet.; [2006]
    Keywords : Organic chemistry; Catalytic; Asymmetric; Reductions; Ketones; Alkenes; Transition metal; Complexes; Organisk kemi;

    Abstract : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. READ MORE

  5. 5. Catalytic Steam Pyrolysis of Biomass for Production of Liquid Feedstock
