1. Selective Catalytic Reduction of NOx with NH3
Sammanfattning : .... LÄS MER
2. 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
3. Structured Ammonia Carriers for Selective Catalytic Reduction
Sammanfattning : Air quality has been one of the long-term focuses in society and has raised people’s concern regarding its amelioration in the post coronavirus disease 2019 (COVID-19) pandemic era. Nitrogen oxides (NOx), including NO and NO2, as one of the most harmful air pollutants, have been stringently monitored in most countries due to their devastating impact on the environment and human health.

4. Selective Catalytic Reduction of NOx with NH3 - Kinetic Modeling and Experimental Studies using Zeolite Based Catalysts
Sammanfattning : Emissions from the combustion of fossil fuel contain several pollutants which can be converted over a catalyst to less harmful products. An efficient way to reduce nitrogen oxides in a lean environment is to apply selective catalytic reduction of these oxides with ammonia (NH3 SCR). LÄS MER
5. 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
