摘　　要：采用水蒸气法对失活V-P/HZSM-5分子筛催化剂进行再生,探讨水蒸气温度、流速及处理时间对再生后催化性能的影响,并用XRD、FTIR、SEM等分析手段对催化剂再生前后的结构进行表征.结果表明,水蒸气再生催化剂的最佳条件为:水蒸气流速为0.3mL.min-1,再生温度为400℃,再生时间为3h.The deactivated V-P/H-ZSM-5 zeolite catalyst was refreshed by distilled water,and its catalytic activity after refreshing was investigated through changing the temperature,velocity or disposed time of distilled water . The catalyst was characteristized with SEM,FTIR,XRD. The experimental results show that,the best refreshed catalyst is obtained with distilled water flow rate of 0.3 mL·min-1,and refreshing for 3 h at 400 ℃.
