SCR Reaction Activity and SO2 Durability Enhancement in Accordance with Manufacturing Conditions of the V/TiO2 Catalysts Lee, Seung Hyun; Seo, Jeong Uk; Byeon, Sang Geun; Hong, Sung Chang;
In this studies, SCR reaction activity and SO2 durability enhancement study on manufacturing conditions of the V/TiO2 catalyst was carried out for the removal of nitrogen oxides generated in the combustion furnace. The catalysts are characterized by XPS, Raman, H2-TPR and SO2-TPD. When the vanadium was contained of 2 wt%, it showed excellent SO2 durability and catalytic activity. and When the tungsten is added as a promotor, the enhancement of reducing ability at a low temperature and reduction of SO2 adsorption capacity improved the reaction activity and SO2 durability. V/W/TiO2 are prepared by the lower pH of vanadium solution, vanadium was highly dispersed on the surface and inhibited the formation of crystalline V2O5. in addition, it was confirmed that this catalyst can be used as excellent resistance to high concentration of CO in the combustion furnace.
