逆流连续重整催化剂再生技术的应用

APPLICATION OF REGENERATION TECHNOLOGY FOR CATALYST OF COUNTERCURRENT CONTINUOUS CATALYTIC REFORMING

从催化剂在反应器间的流向、装填比例、催化剂循环输送以及再生系统工艺安全性等方面介绍了逆流连续重整催化剂再生技术的特点,同时对催化剂再生工艺中可能出现或已存在的问题提出了相应的对策和实际解决措施。在该逆流重整装置工业实际运行中,中国石化石油化工科学研究院研发的PS-Ⅵ催化剂表现出了较高的活性、稳定性以及催化剂持氯能力和耐磨性。

The characteristics of catalyst regeneration technology of countercurrent continuous catalytic reforming were introduced from the aspects of catalyst flow direction,loading ratio,catalyst circulation and process safety of regenerative system.And at the same time,the possible or existing problems in the catalyst regeneration process were discussed.The corresponding countermeasures and practical solutions were suggested.The PS-Ⅵ catalyst developed by SINOPEC Research Institute of Petroleum Processing showed high activity,stability,chlorine holding ability as well as wear resistance in the industrial application.
