摘要:

在催化裂化（ＦＣＣ）提升管反应器的出口处，通常设有快速分离设施，其作用是使反应气与催化剂迅速分离，达到快速中，止汽油裂化等不利的二次反应以提高反应选择的目的。本文论述了国外ＦＣＣ反应油气秘催化剂分离技术的进步，着重介绍了美国Ｍｏｂｉｌ－Ｋｅｌｌｏｇ公司新开发的密闭旋风分离器技术及其在国外ＦＣＣ装置上应用的良好效果。

Abstract:

In order to provide a quick seperation of reactor products and products and catalyst,s avoid the unfavorable secondary reaction such as gasoline cracking etc. and increase the selectivity of reaction process, a rapid seperator is generally installed at th
