FRIPP催化重整预加氢技术开发及工业应用

中国石油化工股份有限公司抚顺石油化工研究院(FRIPP)成功开发了适合加工直馏石脑油、直馏石脑油掺炼焦化汽油等原料的催化重整预加氢技术及与其配套使用的FH-40系列轻质馏分油加氢精制催化剂。工业应用结果表明,FH-40系列催化剂对原料适应性强,加氢脱硫和加氢脱氮活性高,均可达到低于0.5μg/g,稳定性好,是加工轻质馏分油的理想催化剂。除此之外,FRIPP还开发了配套使用的"鸟巢"保护剂、脱砷率大于99%的FDAS-1脱砷剂和容硅能力提高4倍的FHRS-1/FHRS-2捕硅剂,并就催化重整预加氢单元反应系统压力降异常升高问题提出了一系列预防措施和解决方案,取得了较好的应用效果,可以保证工业装置长周期稳定运行。

Development and commercial application of FRIPP pre-hydrogenation technology for catalytic reforming

SINOPEC Fushun Research Institute of Petroleum and Petrochemicals has successfully developed the technology for catalytic reforming pre-hydrogenation suitable for processing feedstocks of straight-run naphtha or straight-run naphtha blended with eoker naphtha and associated supporting FH-40 series highperformance light gas oil hydrofining catalysts. Commercial operation results show that FH-40 series catalysts have a wide adaptability to different feedstocks, higher hydrodesulphurization and hydrodenitrogenation activi- ties and good stability. They are proved to be the ideal catalysts for processing light gas oil. In addition, FRIPP has also developed the supporting ＂bird＇s nest＂ guard catalyst, FDAS-1 de-arsenic catalyst and FHRS-1/FHRS-2 silicon trap catalyst, and proposed a number of preventive measures and solutions for abnor- mal pressure drop rise in the reaction system of catalytic reforming pre-hydrogenation unit. Good application results have been achieved and long-term reliable unit operation can be guaranteed.
