Selective Catalytic Reduction of NO in Gas Turbine Exhaust Gas with NH3

Abstract

This research presents the development of metal oxide catalysts V₂O₅ -WO₃ /TiO₂ having different amount of V and W for the selective catalytic reduction (SCR) of NO by NH₃ . The simulated exhaust gas has the same composition as the exhaust gas of a gas turbine power plant having O2 content as high as 15 %vol. The experiment is carried out in the reaction temperature range 150-450°C. The experimental results show that under the operating conditions studied in this research the catalysts 3V7W, 4V5W, and 4V7W are suitable due to their high activity and wide operating temperature both in the presence and the absence of water vapour.
