摘　　要：对中国石油化工股份有限公司沧州分公司1．0 Mt／a的FCC装置,采用中国石油化工股份有限公司石油化工科学研究院开发的MIP-CGP(Maximizing Iso—Paraffins-Cleaner Gasoline and Propylene)工艺技术进行了改造,装置改造后于2004年6月19日开工。生产标定结果表明:在催化剂活性较低条件下,汽油烯烃体积分数降低到31．9％,下降了14．9百分点;丙烯产率增加了2．97百分点;汽油的辛烷值RON和MON分别增加了1．9和2．0,从而提高了汽油的抗爆指数;汽油中硫含量下降了42．67％;在改善精制汽油性质的同时,还显著提高了总液体产品收率。The FCC unit in Cangzhou Company/SINOPEC revamped with MIP-CGP technology developed by SINOPEC Research Institute of Petroleum Processing having been running normally over half a year since it was started up on June 19, 2004. The performance test results showed that, under lower catalyst MAT, the olefin in FCC naphtha was reduced to 31.9% which was 14.9 percentage lower than before, the propylene yield was increased by 2.97 percent, the RON and MON were 1.9 and 2.0 units higher respectively which improved antiknock index of the gasoline, and the sulfur in FCC naphtha was reduced by 42.67%. In addition to the improvement of FCC naphtha properties, the total liquid yield was also increased.
