Cobalt-based alumina pillared zirconium phosphate catalysts for the selective catalytic reduction of NO by propane.
A series of cobalt containing alumina pillared zirconium phosphate materials have been prepared by ion exchange or by impregnation, and fully characterised. The catalytic behaviour of these materials in the selective catalytic reduction of NO by propane, in excess of oxygen, at temperatures ranging between 350 and 550 degrees C, has been also evaluated. A maximum NO conversion close to 14% is o...
متن کاملSelective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon
The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...
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 کاملCatalytic reduction of SO2 with CH4 to elemental sulfur: A comparative analysis of alumina, copper-alumina and nickel-alumina catalysts
The catalytic reduction of sulfur dioxide with methane to form elemental sulfur has been studied. Al2O3, Cu-Al2O3 and Ni-Al2O3 were examined as catalysts and their performances were compared in terms of SO2 conversion and selectivity. Performance of the catalyst extremely enhanced when nickel and copper were added as promoters. The effects of temperature, SO2/CH4 molar ratio, and reaction...
متن کاملSelective catalytic reduction of nitrogen oxides over a modified silicoaluminophosphate commercial zeolite.
Nitrogen oxides (NOx: NO, NO2) are a concern due to their adverse health effects. Diesel engine transport sector is the major emitter of NOx. The regulations have been strengthened and to comply with them, one of the two methods commonly used is the selective catalytic reduction of NOx by NH3 (NH3-SCR), NH3 being supplied by the in-situ hydrolysis of urea. Efficiency and durability of the catal...
