FD2G催化裂化柴油加氢转化技术工业应用总结

Summary of industrial application of FD2G technology

中国石油化工股份有限公司抚顺石油化工研究院开发的 FD2G 催化裂化柴油加氢转化技术已成功工业应用,在削减催化裂化柴油的同时,提高了汽油等高附加值产品的收率。开工初期,催化剂初期活性稳定后汽油产品的研究法辛烷值可以达到 90.0,随着运行时间的延长,汽油产品的研究法辛烷值继续升高。通过工业应用结果分析了 FD2G 装置掺炼直馏柴油、重整重芳烃等原料的可行性,以及掺炼不同原料对汽油产品性质的影响。通过工艺条件的优化,在运行中末期逐渐提高反应压力可以有效延缓催化剂失活速率,精制反应器最高点温度提温速率为 0.004 0 ~ 0.008 5 ℃/d,转化反应器最高点温度提温速率为 0. 003 2 ~ 0. 004 4 ℃/d,实现了工业装置的长周期运行,运行周期不低于 36 个月。

FD2G LCO hydroconversion technology developed by FRIPP has been successfully applied in industry. It can decrease the amount of LCO while improving the yield of high value-added products such as gasoline. At the beginning of start-up,RON of gasoline products can reach 90. 0 after the initial activity of the catalyst is stabilized. RON will continue to increase as running time prolongs. Through the industrial application results,the feasibility of blending SRGO,reforming heavy aromatics in FD2G unit and the effect of blending different feed on the properties of gasoline products are analyzed. Through optimization of process conditions,the catalyst deactivation rate can be effectively delayed by gradually increasing the reaction pressure during the mid-to-late operation period. The highest temperature rising rate of refining reactor is 0. 004 0 ~ 0. 008 5 ℃/d. The highest temperature rising rate of reforming reactor is 0. 003 2 ~ 0. 004 4 ℃/d. It achieves long-term running with an operating cycle of more than 36 months.
