  2. 6. Biomass and Natural Gas Hybrid Combined Cycles

    Author : Miroslav Petrov; KTH; []
    Keywords : biomass; naturalgas; hybrid; combined cycle; gas turbine; internal combustion engine; simulation; electrical efficiency; total efficiency;

    Abstract : Biomass is one of the main natural resources in Sweden.Increased utilisation of biomass for energy purposes incombined heat and power (CHP) plants can help the country meetits nuclear phase-out commitment. READ MORE

  4. 7. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels

    Author : Nicolas Berguerand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Fuel Conversion; Chemical-Looping Combustion; Oxygen Carrier; Ilmenite; Carbon Dioxide Capture; Oxygen Transfer; Gas Conversion; Oxygen Demand;

    Abstract : Chemical-looping combustion (CLC) is a new fuel conversion technology with inherent CO2 capture. In this process, the fuel and the combustion air are never mixed and the oxygen is transferred to the fuel via an oxygen carrier in the form of a metal oxide circulating between two reactors, e.g. READ MORE

  5. 8. Compact diode-pumped solid-state lasers

    Author : Stefan Spiekermann; KTH; []
    Keywords : visible lasers; UV lasers; solid-state lasers;

    Abstract : Compact diode-pumped solid-state lasers (DPSSL) arecontinuously replacing traditional gas lasers as well asenabling completely new technology. However, compact and costefficient designs are required to satisfy end-user demands. Theaim of this thesis was therefore to investigate novel laserdesigns for given applications considering these demands. READ MORE

  6. 9. Determination of Volatile Sulfur Compounds in Air and other Gas Matrices : Development and Applications of Solid-Phase Microextraction

    Author : Fräs Annika Andersson; Bo Svensson; Josep M. Bayona; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Volatile sulphur compounds (VSCs) are frequently emitted during bioindustrial activities, such as production of biogas, sewage treatment, landfilling, pulpmilling, and the slaughtering of animals and meat processing. VSCs are reactive and malodorous, and they can also be detrimental to human health, therefore it is of great interest to be able to analyze these compounds. READ MORE

  7. 10. Intrinsic kinetics of some high temperature gas-solid reactions

    Author : Ioannis Arvanitidis; KTH; []
    Keywords : ;

    Abstract : Many materials processes are based on gas-solid reactions.An understanding of the mechanisms underlying these reactionsis essential for optimization of the process parameters andinvention of new process routes. READ MORE
