1. Studies on Lean NOx Reduction with Ammonia. Catalysts and Sensors
Abstract : 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. READ MORE

2. Structured Ammonia Carriers for Selective Catalytic Reduction
Abstract : 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.

3. Ammonia-Based Post-Combustion Capture of Carbon Dioxide
Abstract : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. READ MORE

4. Flow boiling of ammonia and propane in mini channels
Abstract : The environmental concerns in recent times have grown especially after signing Montreal protocol. In the last ten years, researchers have focussed mainly on understanding the boiling and condensation phenomena of HFC refrigerants in minichannels. READ MORE

5. Structured Carbon-Alkaline Earth Metal Halides Composites for Ammonia Storage
Abstract : NOx (NO, NO2) is one of the most harmful air-pollutants from exhaust, resulting in series of environmental problems as well as severe healthy issues for human beings. Selective catalytic reduction (SCR) system is a common approach to eliminate NOx onboard by using ammonia as a reductant. READ MORE
