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. 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.

5. Vehicle emissions abatement: NO oxidation and ammonia SCR
Sammanfattning : The design and the development of catalytic systems for reducing vehicle emissions is a complex task due to the variety of components in a wide range of gas flow and temperature. A complete system is, therefore, composed of a series of catalysts or catalytic systems, each of which is dealing with a particular aspect of the abatement process. LÄS MER
