  2. 1. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008

    Author : Erik Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IMO; SOx; global cap; Annex VI; MARPOL; air pollution; ships; sulphur oxides; policy-making; emissions;

    Abstract : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

  4. 2. Slag, Steel, Ladle and Non-metallic Inclusions Equilibria in an ASEA-SKF Ladle Furnace

    Author : Kamrooz Riyahimalayeri; Malin Selleby; Johan Björkvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clean steel; Top slag; Non-Metallic Inclusions; Oxides; Vacuum Degassing; Deoxidation; Desulphurization; Equilibrium; Computational Thermodynamics; Scanning electron microscopy;

    Abstract : This study explores the possibility of prediction and modification of some of the physicochemical properties of non-metallic inclusions by considering top slag-steel-ladle equilibria in an ASEA-SKF ladle furnace. To test the reliability of an available computational thermodynamic computer program, the first sub project was done. READ MORE

  5. 3. Materials for High-Temperature Catalytic Combustion

    Author : Anders Ersson; KTH; []
    Keywords : catalytic combustion; catalyst materials; palladium; platinum; bimetallic; garnet; spinel; hexaaluminate; deactivation; sulphur; poisoning; diesel; methane; hydrocarbons;

    Abstract : Catalytic combustion is an environmentally friendlytechnique to combust fuels in e.g. gas turbines. Introducing acatalyst into the combustion chamber of a gas turbine allowscombustion outside the normal flammability limits. READ MORE

  6. 4. Catalytic combustion of gasified waste

    Author : Henrik Kusar; KTH; []
    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

  7. 5. Nanostructured Transition Metal Oxides in Cleantech Application : Gas Sensors, Photocatalysis, Self-cleaning Surfaces Based on TiO2, WO3 and NiO

    Author : Zareh Topalian; Lars Österlund; Andrew Mills; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas sensing; Self-cleaning; photo-fixation; photocatalysis; TiO2; WO3; NiO; Surface engineering; Ytbehandlingsteknik; Functional materials; Funktionella material; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : This thesis focuses on the application of nanocrystalline transition metal oxide TiO2, WO3 and NiO thin films in new “green” building technologies. Specifically, their physicochemical properties in photocatalytic, self-cleaning and gas sensing applications are studied. READ MORE
