1. Studies on Lean NOx Reduction with Ammonia. Catalysts and Sensors
Sammanfattning : Selective catalytic reduction of NOx with ammonia, NH3-SCR, is a promising technique to reduce NOx under lean conditions, e.g. in diesel engine exhausts. The main objective of this thesis was to gain further understanding of key parameters affecting the performance of catalysts and sensors for NH3-SCR. LÄS MER
2. Studies on metal oxide catalysts for selective catalytic reduction of NOx with NH3 -Influence of preparation procedure and feed gas transients
Sammanfattning : .... LÄS MER
3. Catalytic formation of ammonia from nitric oxide
Sammanfattning : The emission of nitrogen oxides (NOx) from automobiles results in severe environmental and biological effects. Passive selective catalytic reduction (passive SCR) of NOx with ammonia (NH3) is a proposed method for abatement of NOx emissions in net lean-burn gasoline passenger vehicles. LÄS MER
4. Modeling of post-combustion carbon capture in power plants and process industries - partial capture and load following conditions
Sammanfattning : Carbon capture and storage (CCS) is recognized as a potent technology for the mitigation of global warming, since it can significantly reduce CO2 emission from large point source emitters. Post-combustion CO2 capture using chemical absorption is a versatile end-of-pipe technology that can be implemented at all point sources of CO2, such as a power production facility or industrial plant.
