连续重整高碳催化剂对再生系统开工的影响

Impact of high-coke catalyst on start-up of regeneration system of continuous catalytic reformer

介绍了在采用法国IFP工艺技术的连续重整装置催化剂再生系统内,采取"高温、高氧、低循环速率"催化剂"黑烧"等措施,解决检修后开工过程中再生系统内部分高碳含量催化剂所带来的问题,如再生器床层超温等,使催化剂再生实现"黑烧"转"白烧",再生系统操作恢复正常。建议今后在装置内增加高碳催化剂分离设施,以减轻检修开工后其对再生系统的冲击。

＂Black burning＂ was practiced to regenerate catalyst of CCR of IFP process at high temperature, high oxygen content and low circulation rate to solve the problems such as excessive regenerator bed temperature, etc, resulted from high coke on some of catalysts in the regeneration system during the re-startup after turnaround. The ＂black burning＂ turned to ＂white burning＂ catalyst regeneration and the normal operation of regeneration system was restored. Separation facilities for high-coke catalysts are proposed to be installed in the unit to mitigate their shock on the regeneration system after re-startup of the unit.
