The commercial application of LHO1 catalyst tailored for MIP technology at the 0. 6 Mt/a FCCU of Yulin Refinery was introduced. Results showed that under similar feedstock properties in comparison with the catalyst in base case, the olefin content of gasoline decreased from 37. 3% to 28. 1%, which could meet the requirement of National Emission Standard Id- At the same time,the diesel yield increased slightly,product distributions and product qualities were improved in some ways,catalyst consumption decreased and the total energy consumption of the unit reduced as well,resulting in a better e-conomic benefit.%介绍MIP工艺专用催化剂LHO-1在陕西延长石油(集团)有限责任公司榆林炼油厂600 kt/a催化裂化装置上的工业应用情况.结果表明,在原料油性质基本不变的情况下,使用LHO-1专用催化剂后,汽油中烯烃体积分数由37.3％降至28.1％,达到国Ⅲ标准要求,同时柴油收率略有提高,产品的分布和质量得到了一定改善,催化剂单耗下降,装置总能耗有所降低,提高了装置的经济效益.
