摘　　要：为满足汽油升级至国Ⅵ标准的要求,2019年中国石油玉门油田分公司炼油化工总厂对原80 kt/a异构化装置进行了技术改造,增加了原料油干燥再生系统和循环氢干燥再生系统,将异构化催化剂更换为中国石化石油化工科学研究院开发的RISO-C固体超强酸催化剂,以重整装置拔头油为原料,增产异构化汽油,有效降低汽油池烯烃含量和芳烃含量,为生产国Ⅵ汽油打下坚实基础。改造后异构化装置于2019年11月一次开车成功,2020年9月标定结果表明,异构化汽油研究法辛烷值大于84,C_(5)异构化率大于68%,C_(6)异构化率大于83%,均达到设计指标要求,说明RISO-C固体超强酸催化剂活性良好,能满足异构化装置长周期安全平稳运行的需求。To meet ChinaⅥgasoline standard,the PetroChina Yumen Oilfield Company Oil Refining and Petrochemical General Plant completed the technical innovation of original C_(5)/C_(6) isomerization unit,added the feedstock and circulating hydrogen drying and regeneration system,and replaced the original catalyst by the solid super-acid catalyst RISO-C.This unit could convert the reforming topped oil to gasoline blending component with high octane number,which effectively reduces the olefins and aromatics content of ChinaⅥgasoline pool.The revamped unit was started successfully in November,2019,and the results of performance test of unit show that the isomerization ratio of C_(5) is more than 68%,the isomerization ratio of C_(6) is more than 83%,reaching the target of design and demonstrating the excellent performance of catalyst,which can meet the need of long term run of unit.
