The Selective Catalytic Reduction of NOx with NH3 over Titania Supported Rhenium Oxide Catalysts
Titania supported vanadium oxide catalysts have been demonstrated to be very efficient catalysts for the selective reduction of NOx with NH3 and have found widespread industrial application for the control of NOx emissions from stationary sources (1). Characterization studies have demonstrated that supported vanadium oxide catalysts consist of a two-dimensional metal oxide overlayer on the oxid...
متن کاملLow temperature selective catalytic reduction of NOx with NH3 over Mn-based catalyst: A review
The removals of NOx by catalytic technology at low temperatures (100–300 °C) for industrial flue gas treatment have received increasing attention. However, the development of low temperature catalysts for selective catalytic reduction (SCR) of NOx with ammonia is still a challenge especially in the presence of SO2. The current status of using Mn-based catalysts for low temperature SCR of NOx wi...
متن کاملSelective Catalytic Reduction of NOx with Methane over Ag-alumina Catalysts in High-content SO2 Gas Streams
In this work, we investigated the performance of Ag-alumina catalysts for the SCR of NO with methane in gas streams with a high concentration of SO2, typical of coal-fired power plant flue gas. Agalumina catalysts were prepared by co-gelation and nitric-acid leaching was used to remove weakly bound silver species from the catalyst surface [1, 2]. We found that SO2 has a dramatic inhibitory effe...
متن کاملMercury oxidation over selective catalytic reduction ( SCR ) catalysts
The vanadium-based SCR catalyst used for NOx-control promotes the oxidation of elemental mercury Hg to Hg in flue gases from coal-fired power plants. Hg is water soluble and can effectively be captured in a wet scrubber. This means that the combination of an SCR with a wet FGD can offer an effective control option for mercury. Laboratory experiments have been carried out to elucidate and quanti...
متن کاملEnhancing selective catalytic reduction of NOx with alternative reactants/promoters
The hydrocarbon-selective catalytic reduction (HC-SCR) activity of an Ag/Al2O3 catalyst was investigated. The function on catalytic NOx reduction of different fuel properties using alternative reactants such as gas-to-liquid (GTL) and butanol was studied. This work proves that such improvements are due to the high reactivity, polarity and diffusivity of butanol within the catalyst enhancing NOx...
