  2. 1. Catalytic partial oxidation of methane over nickel and ruthenium based catalysts for GTL applications

    Author : Jorge A. Velasco; Magali Boutonnet; Sven Järås; Henrik Kusar; Stan Kolaczkowski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalytic partial oxidation; carbon formation; GTL; nickel; ruthenium; synthesis gas; thermodynamic equilibrium.; Chemical Engineering; Kemiteknik;

    Abstract : The Gas to Liquids (GTL) process is an important alternative for monetizing natural gas through the production of long-chain liquid hydrocarbons, e.g. diesel fuel. READ MORE

  4. 2. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

    Author : Monica Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

    Abstract : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. READ MORE

  5. 3. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine

    Author : Monica Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Alternative Fuels; Fischer-Tropsch; GTL;

    Abstract : Alternative fuels for Diesel engines include ester-based fuels (derived from sources such as rapeseed, soybeans and palm oil), dimethyl ether, and various synthetic fuels. Use of these fuels could contribute to a cleaner environment, reduce global warming and improve the human health by reducing levels of harmful emissions. READ MORE

  6. 4. Life Cycle Assessment of Novel Biomethane Systems : energy performance and climate impact

    Author : Elham Ahmadi Moghaddam; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Climate mitigation and supply of renewable energy are global challenges. The main cause of climate change is anthropogenic activities, including consumption of fossil energy sources and land use change. Biomethane, a biomass-derived renewable energy carrier, is interchangeable with fossil-based natural gas and can provide energy services (e.g. READ MORE

  7. 5. Optical Characterization of Solar Collectors form Outdoor Measurements

    Author : Anna Helgesson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. READ MORE
