摘　　要：针对某合成氨企业净化车间变换系统催化剂频繁出现失活现象,造成经济损失并影响到生产装置稳定运行的情况,对可能导致变换催化剂失活的原因进行了分析,确定了催化剂中毒是由原料煤中的有机氯含量高引起的,同时提出了源头控制、过程管理及终端治理的应对措施。Frequent catalyst deactivation of the shift system in the purification unit of some ammonia plant leads to economic loss and affects stable operation of the plant. This paper analyzes the possible reasons causing the catalyst deactivation, figures out that catalyst poisoning is the result of high content of organic chloride in the feed coal and proposes the countermeasures of source control, process management and end-of-pipe treatment.
