16. Exploring The Versatility Of Ionic Liquids : From fundamental understanding to materials inspired from ionic liquids
Abstract : Ionic liquids (ILs) have gained popularity as “green” and safe replacements for conventional organic solvents. They are defined as ionic salts displaying a melting point below 100 °C. Some of their unique characteristics also include negligible vapour pressure, good electrical conductivity as well as good thermal and chemical stability. READ MORE

17. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production
Abstract : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. READ MORE

18. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production
Abstract : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). READ MORE

19. The use of Fenton chemistry for reducing the refining energy during TMP production : the effect of free ferrous and free or chelated ferric ions
Abstract : The potential of using acid hydrogen peroxide under Fenton conditions to lowerthe electrical energy consumed during the production of Black spruce (Piceamariana) thermomechanical pulp (TMP) was investigated in pilot scale. Thechemical system, which consisted of ferrous sulphate, hydrogen peroxide andoptionally an enhancer (such as a chelating agent), was evaluated as an inter-stagetreatment. READ MORE

20. A study of an autogenous slag for steel production with consideration of possible vanadium extraction
Abstract : The thesis discusses the use of the autogenous slag that forms from the residual oxides present in hydrogen reduced iron (H-DRI) pellets during melting. The studies are motivated by a better understanding of how H-DRI affect the steelmaking operations. READ MORE
