摘要

采用沉淀过饱和浸渍法制备CaO/ZrO_2固体碱催化剂,考察了催化水解温度对氟利昂(HCFC-22)降解率的影响以及催化剂的使用寿命。结果表明,当水解温度为360℃时,降解率达到最大为97.09%,且该催化剂在连续反应40 h后,HCFC-22的降解率仍保持在60%以上。
        CaO/ZrO_2 solid base catalyst was prepared by precipitation supersaturation impregnation.The effect of the catalytic hydrolysis temperature on the degradation rate of freon(HCFC-22) and the service life of the catalyst were also investigated.The results showed that the maximum degradation rate reached 97.09% when the hydrolysis temperature was 360 ℃.The degradation rate of HCFC-22 remained above 60% after contiuous reaction of 40 h.
