SCR烟气脱硝催化剂V2O5-WO3/TiO2性能研究
Preparation of V2O5-WO3/TiO2 catalyst and properties of reduction NOx
摘要
Abstract
V2O5-WO3/TiO2 catalysts have been prepared by the impregnation method. Their activity and performance in the selective catalytic reduction in NOx with NH3 were characterized. The results showed that the response window was widened of the WO3 being introduced, with the WO3 content increasing, NO removal efficiency increase appreciably, especially at the high temperature. The catalyst has best effect when the WO3 content was 8%, in the response temperature of 250-400 ℃. NO removal efficiency can reach to 95%, even the NO removal efficiency have been attained 89. 19% at the 450 ℃. In addition, the influence of space velocity, oxygen concentration, NO initial concentration and NH3/NO ration for the catalyst activity have been further studied.关键词
