摘　　要：以酸处理蒙脱土K10为载体,采用浸渍法制备出环境友好的蒙脱土负载CAN催化氧化剂,利用BET和IR对催化剂进行了表征。考察了活化温度和活化时间对催化活性的影响。实验结果表明,将MMT-CAN负载催化剂在120℃下活化4 h其比表面积由活化前的70.36 m2/g提高到107.06 m2/g,催化活性明显提高。Using acid-treated montmorillonite K10 as catalyst supporters,environmentally friendly montmorillonite-supported CAN catalysts were prepared through impregnation-evaporation method,and its structure was characterized by BET and IR techniques. The effects of activated temperature and time on catalyst performance were investigated. The experimental results show that the BET area of catalyst which activated at 120 ℃ for 4 h was improved from 70. 36 m2/ g to 107. 06 m2/ g,the catalyst activity has been improved obviously.
