16. Application of scattered sunlight spectroscopy for quantification of gas emissions from anthropogenic and natural sources
Abstract : Monitoring of gas emissions from natural and anthropogenic sources is of importance due to their negative effects on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE

17. Experimental and kinetic studies of H2 effect on lean exhaust aftertreatment processes: HC-SCR and DOC
Abstract : With a growing concern to lower greenhouse gas emissions from road transportation, lean burn and diesel engines will keep playing an important role in the future. Development of a highly efficient and durable process to reduce NOx to N2 becomes a challenging issue especially in the presence of ample O2 concentration as in lean burn exhaust. READ MORE

18. Selective Catalytic Reduction of NOx with NH3 - Kinetic Modeling and Experimental Studies using Zeolite Based Catalysts
Abstract : 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). READ MORE

19. Vehicle emissions abatement: NO oxidation and ammonia SCR
Abstract : 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. READ MORE

20. 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
