6. A Process Integration Approach to Assessing Possibilities for Improved Material Efficiency in Nordic ore-based Iron- and Steelmaking Systems
Abstract : Iron- and steel production is a material- and energy intensive industrial activity. The production of one tonne of steel commonly results in some 400 kilograms of residual materials such as metallurgical slags, dusts, sludge and scales generated in the processes. READ MORE

7. Properties of oxygen carriers based on natural and waste materials at high degrees of reduction
Abstract : Oxygen carriers play an important role in multiple energy conversion processes, such as chemical-looping technology and oxygen-carrier-aided combustion. This thesis particularly explores how a high reduction degree of an oxygen carrier can affect its performance. READ MORE

8. Development and Characterisation of Oxygen-Carrier Materials for Chemical-Looping Combustion
Abstract : For combustion with CO2 capture, chemical-looping combustion (CLC) with inherent separation of CO2 is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, a gaseous fuel is oxidized by an oxygen carrier, e.g. READ MORE

10. Catalytic tar cleaning of biomass-derived gas with simultaneous catalyst regeneration
Abstract : 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.
