1. Catalytic tar cleaning of biomass-derived gas with simultaneous catalyst regeneration
Sammanfattning : Tar cleaning of raw gas from biomass gasification is a necessary operation before the gas can be used as feedstock for synthetic fuels. The technology for gas cleaning that is commercially available today (scrubber systems), is associated with problems like heat penalties and loss of the chemically stored energy within the tars.

2. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas
Sammanfattning : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. LÄS MER
3. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Sammanfattning : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. LÄS MER
4. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis
Sammanfattning : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.

5. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes in power plants
Sammanfattning : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.
