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

    Author : Toni Karlsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Synthesis, Electrophoretic Deposition, and Characterization of Nanostructured Thermoelectric Materials

    Author : Hazal Batili; Muhammet Toprak; Oliver Fenwick; KTH; []

    Abstract : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. READ MORE

  5. 3. Lowcoordinated Silicon and Hypercoordinated Carbon : Structure and Stability of Silicon Analogs of Alkenes and Carbon Analogs of Silicates

    Author : Anders M. Eklöf; Henrik Ottosson; Sten Lunell; Thomas Müller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; silenes; zwitterionic silenes; silenolates; reverse polarization; natural resonance theory; hypervalent carbon; hypercoordinated carbon; thermolysis; lowcoordinated silicon; Organic chemistry; Organisk kemi;

    Abstract : 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. READ MORE

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

    Author : Andreas Lundström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea; SCR; decomposition; CYA; HNCO; NH3; CFD; thermolysis;

    Abstract : 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. READ MORE

  7. 5. Urea Decomposition for Urea-SCR Applications

    Author : Andreas Lundström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NOx; Selective Catalytic Reduction; Urea; Thermolysis; Modeling; Computational Fluid Dynamics;

    Abstract : 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. READ MORE
