16. 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.

17. Selective Catalytic Reduction of NOx: Deactivation and Regeneration Studies and Kinetic Modelling of Deactivation
Sammanfattning : Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. LÄS MER

19. Pulsating Combustion - Combustion Characteristics and Reduction of Emissions
Sammanfattning : In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion.

20. NOx Abatement Technique for Marine Applications - Improved SCR Systems
Sammanfattning : Growing awareness of the environmental implications of emissions of nitrogen oxides (NOX), such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOx legislations within the framework of IMO, with the most stringent legislation, Tier III, representing a NOx reduction of approximately 80% compared with today’s engines. Several NOx abatement technologies are available on the market, the most effective of which may be Selective Catalytic Reduction (SCR). LÄS MER
