摘　　要：利用助凝剂1,2-环氧丙烷(PO)对Cu_(a)ZrCeTiO_(x)催化剂进行设计与优化,考察了PO对催化剂性能的影响。结果表明,催化剂制备的最优参数为PO添加质量为7.5 g、老化时间为24 h、老化温度为60℃、焙烧温度为500℃。以二氯甲烷为处理对象,在40 h的测试时间中,整体转化率始终维持在80%以上,且尾气的CO_(2)选择性下降幅度较小,依然具备较强的深度催化氧化能力。Cu_(a)ZrCeTiO_(x) catalyst is designed and optimized by using 1,2-propylene oxide(PO)coagulant aid,and the influence of PO on the performance of the catalyst is studied.Results show that the optimal parameters for catalyst preparation are as follows:the dosage of PO is 7.5 g,the aging time is 24 h,the aging temperature is 60℃,and the calcination temperature is 500℃.Taking dichloromethane as the treatment object,during the 40-hour test period,the overall conversion rate always maintains above 80%,and the selectivity of CO_(2) in the tail gas declines a little,showing that the catalyst still possesses a relatively strong ability for deep catalytic oxidation.
