  1. 1. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Toni Karlsson; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Sammanfattning : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. LÄS MER

  2. 2. Lowcoordinated Silicon and Hypercoordinated Carbon Structure and Stability of Silicon Analogs of Alkenes and Carbon Analogs of Silicates

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anders M. Eklöf; Uppsala universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silenes; zwitterionic silenes; silenolates; reverse polarization; natural resonance theory; hypervalent carbon; hypercoordinated carbon; thermolysis; lowcoordinated silicon; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Sammanfattning : Quantum chemical studies on lowcoordinated group 14-16 compounds have been performed. This thesis focuses particularly on silenes influenced by reverse Siδ-=Cδ+ bond polarization. Hypercoordinated carbon compounds are also studied. LÄS MER

  3. 3. Computational Fluid Dynamics and Experimental Studies of the Urea-SCR System

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Lundström; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea; SCR; decomposition; CYA; HNCO; NH3; CFD; thermolysis;

    Sammanfattning : Volatile emissions produced by the burning of fossil fuels may be converted on a catalyst to less harmful products. During lean combustion an excess of oxygen in the exhaust gases together with a catalyst effectively oxidizes carbon monoxide and hydrocarbons into carbon dioxide and water. LÄS MER

  4. 4. Urea Decomposition for Urea-SCR Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Lundström; [2010]

    Sammanfattning : Volatile emissions produced by the combustion of fossil fuels may be converted on a catalyst to less harmful products. During lean combustion an excess of oxygen in the exhaust gases together with a catalyst effectively oxidizes carbon monoxide and hydrocarbons into carbon dioxide and water. LÄS MER

  5. 5. Stereoselective Nucleophilic Additions to Aldehydes and Synthesis of α-Amino-β- Hydroxy-Esters

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jakob Danielsson; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asymmetric induction; stereochemical models; Mukaiyama; polar Felkin-Anh; Cornforth-Evans; 1; 3-dipole; aziridine; cycloaddition; amino alcohol; carbonylation; Heck reaction; quaternary stereocenter;

    Sammanfattning : This thesis deals with the development of new reaction methodology as well as stereochemical investigations.The first part concerns the investigation of 1,2- and merged 1,2- and 1,3- asymmetric induction in Mukaiyama aldol additions to α-heteroatom and α,β- heteroatom substituted aldehydes respectively.
