摘要
介绍了清江石油化工有限公司直馏汽油进催化裂化提升管改质情况。结果表明直馏汽油改质后催化裂化汽油辛烷值（ＲＯＮ）仍可达９０，液体产品收率提高。催化裂化汽油收率提高了１．２９个百分点，柴油收率下降了约１个百分点。同时催化裂化装置运行周期延长。
Straight-run naphtha upgrading by catalytic cracking riser in Qingjiang Petrochemical Company was introduced. The results showed that after upgrading, the research octane number of catalytic gasoline can still reach 90, while liquid product yield enhanced. The yield of catalytic cracking gasoline increased by1 .29 percentage points and the diesel yield decreased by 1 percentage point. Meanwhile,the running period of FCCU was prolonged.
