1. Atomic Scale Design of Clean Energy Materials : Efficient Solar Energy Conversion and Gas Sensing
Sammanfattning : The focus of this doctoral thesis is the atomic level design of photocatalysts and gas sensing materials. The band gap narrowing in the metal oxides for the visible-light driven photocatalyst as well as the interaction of water and gas molecules on the reactive surfaces of metal oxides and the electronic structure of kaolinite has been studied by the state-of-art calculations.

2. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass
Sammanfattning : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. LÄS MER
3. Renewable gas in a Swedish context
Sammanfattning : In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. LÄS MER
4. Hybrid Solar Gas-Turbine Power Plants : A Thermoeconomic Analysis
Sammanfattning : The provision of a sustainable energy supply is one of the most importantissues facing humanity at the current time, and solar thermal power hasestablished itself as one of the more viable sources of renewable energy. Thedispatchable nature of this technology makes it ideally suited to forming thebackbone of a future low-carbon electricity system. LÄS MER
5. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts
Sammanfattning : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. LÄS MER
