1. Study of Catalyst Deactivation in Three Different Industrial Processes
Abstract : Deactivation of catalysts were investigated focusing on three industrial processes: 1) Selective Catalytic Reduction (SCR) for abatement of NOx from biomass combustion using V2O5-WO3 /TiO2 catalysts; 2) Catalytic oxidation of volatile organic compounds (VOC) from printing industries using a Pt/γ-Al2O3 catalyst; and 3) Ni and Pt/Rh catalysts used in steam reforming reaction of bio-syngas obtained from biomass gasification.The aim has been to simulate industrial conditions in laboratory experiments in order to comprehend influence of compounds affecting catalysts performance.

3. Selective Catalytic Reduction of NOx: Deactivation and Regeneration Studies and Kinetic Modelling of Deactivation
Abstract : 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. READ MORE

4. Deactivation of Catalysts and Reaction Kinetics for Upgrading of Renewable Oils
Abstract : The transport sector is one of the main contributors of greenhouse gas emissions in the world. Advanced biofuels from renewable oils can play a decisive role in reducing carbon emissions from the transport sector. Advanced biofuels from waste streams like tall oil, used cooking oil etc. READ MORE

5. Metal-exchanged zeolites for NH3-SCR applications - Activity and Deactivation studies
Abstract : Emissions of nitrogen oxides (NOX) formed during the burning process in internal combustion engines is a major contributor to global air pollutions. One effective way to reduce NOX in lean environments, i.e. oxygen excess is selective catalytic reduction with ammonia (NH3-SCR). READ MORE
