| 摘 要： | 以活性半焦为载体,采用等体积浸渍硝酸铜溶液制备CuO/SC催化剂低温脱除模拟烟气中的NOx,利用BET、XRD和SEM等方法对CuO/SC催化剂进行了表征,采用固定床反应器测定了CuO/SC催化剂的脱硝活性,考察了CuO负载量、反应温度、空速、O2浓度和H2O浓度对CuO/SC脱硝率的影响。结果表明,当CuO/SC催化剂的载铜量为1%、温度70℃、空速1000h-1、O2浓度5%时,脱硝效果最好;并且分析了水蒸气对催化剂脱硝性能的毒化作用,当水蒸气存在时,穿透时间由15h缩短为9.5h。

| Abstract: | CuO/SC catalysts were prepared by incipient wetness impregnation and characterized by BET, XRD and SEM. Their performance for NO oxidation was tested in a fixed bed reactor. The influence of CuO content, reaction temperature, space velocity, concentration of O2 and H2O on NO catalytic oxidation activity were investigated. The results show that CuO/SC with 1% CuO loading had the highest activity at 70 ℃, 5% of O2 and 1 000 h-1 of GHSV. In addition, the poisonous effect of water vapor on catalytic oxidation activity was also analyzed. When water vapor was introduced into the feed gas, breakthrough time is reduced from 15 h to 9.5 h. |
