摘　　要：以ZSM-5分子筛为载体,通过浸渍法制备10%CuO/ZSM-5(金属氧化物质量占载体质量)催化剂,以CH4为还原气,考察不同焙烧温度和焙烧时间对催化剂脱硫脱硝性能的影响。XRD和TPR的表征结果显示,最佳焙烧条件为550℃下焙烧4 h,在此焙烧条件下,10%CuO/ZSM-5催化剂达到的最高脱硝脱硫率分别为90.6%和98.8%。CuO/ZSM-5 catalyst was prepared by using molecular sieve ZSM-5 as the supporter and being impregnated with copper oxide,and its performance of desulfuration and denitrification under different calcination temperatures and times was investigated using CH4 as reducer.The results of XRD and TPR characterization showed that the best baking conditions were 550℃ and 4 hours,and the highest rates of desulfuration and denitration were 90.6% and 98.8%,respectively under these conditions.
