摘　　要：通过对丙烯腈催化剂使用过程中出现的性能下降原因进行分析,找出其关键影响因素为Mo组分的流失和催化剂被部分还原。采用适当的原料和工艺再生后,催化剂性能明显恢复,装置部分置换再生催化剂后反应成绩得到较好的改善。Reasons of deactivation of catalysts for acrylonitrile from propylene were discussed and a method of reactivation of catalysts and replenishment of molybdenum was proposed. The plant - scale application showed that the activities and molybdenum contents of catalysts were improved and stabilized remarkably.
