Abstract: The influences of practical technological conditions of SNOX method on the catalytic removal efficiencies of NO○x and SO2 from flue gas were studied experimentally. For studying the catalytic reduction reaction of NO○x, CuO/γ-Al2O3catalyst was prepared by impregnation method. The influences of reaction temperature, space velocity, n(NH3)/n(NO○x) and SO2 concentration on the conversion rate of NO○x were investigated. For studying the catalytic oxidation reaction of SO2, V2O5 catalyst was applied. The influences of reaction temperature, space velocity, n(O2)/n(SO2) on the conversion rate of SO2 were investigated. Based on the experimental results, kinetic calculations for the reactions were carried out. The results showed that, under the optimum conditions, the reduction rate of NO○x can reach 87.5%, and after two stages of oxidation, the conversion rate of SO2 can reach 94.3%.
