  2. 1. Synthesis gas from black liquor : trace components and methanol synthesis

    Author : Caroline Häggström; Mats Lindblom; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The common European Energy and Climate policy states that in 2020 the share of biofuels for inland transports should be 10 %. Such a stipulation calls for a commercially sustainable biofuel production. READ MORE

  4. 2. Study and Development of Techniques to Improve Engine Stability and Reduce Emissions from Natural Gas Engines

    Author : Patrik Einewall; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; Motors and propulsion systems; Low Emissions ; Natural Gas Engines ; EGR ;

    Abstract : The objective of this thesis was to find ways to improve combustion and reduce emissions from supercharged natural gas engines. In-cylinder flow measurements were made with laser doppler velocimetry, LDV, heat release was calculated from cylinder pressures and emissions were measured at various locations. READ MORE

  5. 3. Pathophysiology and treatment of chlorine gas-induced lung injury : an experimental study in pigs

    Author : Jianpu Wang; Kai Knudsen; Östergötlands Läns Landsting; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : One of the most threatening scenarios in disaster medicine is the accidental release of toxic gases with the exposure of many people. In this respect, chlorine gas remains a significant threat due to its abundant use and transport through densely populated areas in modem society. READ MORE

  6. 4. Modelling and Simulation of Thermal Radiation in Biomass Combustion

    Author : Thomas Nilsson; Förbränningsfysik; []

    Abstract : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. READ MORE

  7. 5. Numerical Investigation of Radial Turbines Subject to Pulsating Flow

    Author : Roberto Mosca; Mihai Mihaescu; José Ramón Serrano; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : In the optic of a more sustainable society, research and development of highly efficient fluid machines represent a fundamental process to satisfy the rapidly growing energy needs of the modern world. Radial turbines are characterized by higher efficiencies for a larger range of inflow conditions compared to axial turbines. READ MORE
