1. Closing the Loop by Combining UASB Reactor and Reactive Bed Filetr Technology for wastewater Treatment : Modelling and Practical Approaches
Sammanfattning : A laboratory-scale upflow anaerobic sludge blanket (UASB) reactor followed by a packed bed reactor (PBR) filled with Sorbulite® in the lower part and Polonite® in the upper part was used to treat household wastewater in a 50-week experiment. A model was developed to describe the performance of the UASB reactor, including mass transfer through the film around anaerobic granules, intra-particle diffusion and bioconversion of the substrate.

2. From torrefaction to gasification : Pilot scale studies for upgrading of biomass
Sammanfattning : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

3. Pyrolysis of Biodegradable Waste for Negative Carbon Emissions
Sammanfattning : Bioenergy with Carbon Capture and Storage represents a crucial technology that enables an energy production with negative carbon emissions, which is needed to achieve global climate goals. Appropriated management of biodegradable waste, including biodegradable lignocellulosic waste, sewage sludge, organic fraction of municipal solid waste, can make this contribution. LÄS MER
4. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production
Sammanfattning : 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. LÄS MER
5. Catalytic Reduction of NOx on Heavy-Duty Trucks
Sammanfattning : The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. LÄS MER
