| 摘 要： | 采用了等体积浸渍法制备二氧化钛负载钒氧化物催化剂（V2O5/TiO2）,研究了V2O5负载量、反应温度、烟气流量、氨氮比以及运行时间各因素对NH3选择性催化还原NO反应（SCR）效率的影响.研究结果表明：经过500℃温度下煅烧,烟气流量为200ml/min,负载量为7wt％的V2O5/TiO2催化剂,在400℃温度下反应,NO脱除率可达70.5％.

| Abstract: | V2O5/TiO2 catalyst was prepared by impregnation method for low temperature se- lective catalytic reduction （SCR） of NO with NH3. The effects of different V205 loadings, reaction temperatures, and flow rates of flue gas, Ammonia ratio and reaction time were studied. The results showed that NO conversion of 7wt%V2OJTiO2 catalysts can reach 70.53% under 400~C when the flow rates was 200ml/min flow rates and the calcination temperature was 500~C. |
