2. Chemical Transformation of Inorganic Species in Thermochemical Conversion of Waste-Derived Fuels - The Role of Oxygen Carriers
Sammanfattning : Waste-derived fuels are used increasingly in heat and power production systems in Sweden. Thermal conversion of waste-derived and biomass fuels offers the possibility of achieving carbon dioxide-neutral or even negative emissions. To limit global warming, it is essential to integrate these systems with carbon capture and storage. LÄS MER
3. Investigation of the behaviour of gaseous I2 and RuO4 in different atmospheres
Sammanfattning : During a severe accident several hazardous and radiotoxic fission products can be released and constitute a threat to the environment. Two of the most important fission products are iodine and ruthenium which will be accumulated after inhalation in the human body in the thyroid gland and in the respiratory organs, respectively.

4. Adsorption of Metallic Ions onto Chitosan : Equilibrium and Kinetic Studies
Sammanfattning : Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions.

5. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements
Sammanfattning : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. LÄS MER
