MIP降烯烃技术及其操作探讨

Study on MIP Technology and Its Operating

针对锦西石化重油催化裂化装置MIP技术应用后存在的汽油辛烷值低、柴汽比下降的主要问题,文章分析了MIP的工艺技术思路,结合重油催化装置的生产实际,通过改变一、二反的操作条件,应用专用催化剂,使汽油辛烷值达到88.5～90,柴油收率达到28%～30%,满足了生产要求。

To resolve the main issues of low octane number and dropping diesel-gasoline ratio after MIP technology applications in the heavy oil catalytic cracking facility in Sinopec Jinxi Corporation, the paper analyzed the MIP technology ideas, with the production practice in heavy oil catalytic cracking facility. By changing the operating conditions of the 1st and 2nd reactions, and applying the specialty catalyst, the octane number was brought to the range of 88.5-90, with the diesel yield of 28 % to 30 %. The results met the production requirement.
