摘要
上海石油化工股份有限公司3.30 Mt/a加氢装置设计空速高达2.3 h-1,为了满足高空速条件下稳定生产国Ⅳ标准柴油的要求,采用抚顺石油化工研究院开发的S-RASSG级配技术及配套的FHUDS-2/FHUDS-5催化剂组合体系,在装置运转5个月后,自2010年11月至2011年2月间,在体积空速为1.8～2.2 h-1、反应器入口温度318～325℃、出口温度371～378℃等条件下,加工硫质量分数为0.96%～1.26%的直馏柴油掺兑40%催化柴油及焦化汽柴油混合油,连续生产国Ⅳ标准柴油70 d,精制柴油符合国Ⅳ标准柴油质量指标要求。说明S-RASSG级配技术可以在高空速条件下满足加工直馏柴油掺兑40%二次加工油品混合原料油稳定生产符合国Ⅳ标准清洁柴油的要求,体现了S-RASSG技术配套的FHUDS-2/FHUDS-5组合体系具有活性稳定性好和对原料油适应性强的特点,是高空速条件下加工掺兑较高比例二次加工油品混合油生产国Ⅳ排放标准清洁柴油的理想选择。
The design LHSV of 3.3 MM TPY diesel hydrotreating unit in SINOPEC Shanghai Petrochemical Co.,Ltd was 2.3 h-1.To meet the requirement of producing Guo-Ⅳ standard diesel at high liquid hourly space velocity,the S-RASSG catalyst stack technology and associated FHUDS-2/FHUDS-5 catalysts system developed by SINOPEC Fushun Research Institute of Petroleum and Petrochemicals（FRIPP） were applied.After 5 months＇ operation of the unit,the unit was operating to produce Guo-Ⅳ standard diesel for 70 days from November,2010 to February,2011 under the operating conditions of volumetric space velocity of 1.8~2.2 h-1,318~325 ℃ reactor inlet temperature and 371~378 ℃ reactor outlet temperature with the feedstock of straight-run diesel containing 0.96 w%~1.26 w% of sulfur blended with 40% FCC diesel and coker diesel.All diesel produced has met the Guo-Ⅳ standard specifications.This shows that S-RASSG stack catalyst technology is capable of producing Guo-Ⅳ standard clean diesel from feed of straight-Ⅳrun diesel blended with 40% of oil from downstream units at high space velocity.It also demonstrates that the associated FHUDS-2/FHUDS-5 catalysts system for S-RASSG technology is high in activity and stability and good in adaptability to different feedstocks.It is proved to be a satisfactory selection for producing Guo-Ⅳ standard clean diesel from mixed feedstock of higher blending ratio of oil from downstream units at a higher space velocity.
