1. Catalytic partial oxidation of methane over nickel and ruthenium based catalysts for GTL applications
Sammanfattning : 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. LÄS MER
2. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study
Sammanfattning : 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. LÄS MER
3. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine
Sammanfattning : 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. LÄS MER
4. Life Cycle Assessment of Novel Biomethane Systems : energy performance and climate impact
Sammanfattning : 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. LÄS MER
5. Optical Characterization of Solar Collectors form Outdoor Measurements
Sammanfattning : 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. LÄS MER
