1. Studies of hydrocarbon-assisted selective catalytic reduction of nitrogen oxides - DME as reductant and reaction mechanism over silver/alumina
Sammanfattning : Increasing amounts of carbon dioxide are attaining worldwide growing attention as one probable cause for global warming. Together with the expected peak in oil production and an increasing oil demand, this results in a greater interest in more fuel effective lean burn engines (i.e. operation with excess oxygen).

2. Studies of the Selective Catalytic Reduction of Nitrogen Oxides with Dimethyl Ether
Sammanfattning : Dimethyl ether (DME) is one of the most energy-efficient and low CO2 emitting alternative fuels when produced from biomass. Similar to other vehicles with combustion engines, vehicles running on DME will most likely need after-treatment technologies for the reduction of NOx emissions to meet the most stringent upcoming legislations.
