摘　　要：为满足炼油企业生产国Ⅳ及欧Ⅴ标准清洁柴油的需要,抚顺石油化工研究院(FRIPP)开发了适合不同原料、分别以W-Mo-Ni(Mo-Ni)及Mo-Co为活性金属的FHUDS系列催化剂,并根据加氢反应器内催化剂床层不同的工况条件和反应特点,结合不同类型催化剂的超深度脱硫反应机理,开发了催化剂级配的S-RASSG柴油超深度脱硫技术。工业应用结果表明:采用S-RASSG技术及配套的FHUDS-2/FHUDS-5催化剂体系,加工常压柴油掺兑质量分数为40%左右催化柴油及焦化汽柴油或减压柴油的高硫混合油,在反应器入口压力8.0 MPa,主催化剂体积空速1.85～2.25 h-1、平均反应温度350℃左右等条件下,可以长周期稳定生产硫质量分数小于50μg/g、满足国Ⅳ标准的低硫柴油;加工常压柴油掺兑质量分数为30%左右减压柴油及少量焦化柴油的混合油,在反应器入口压力8.0MPa,主催化剂体积空速1.85 h-1、平均反应温度350℃左右等条件下,可以稳定生产硫质量分数小于10μg/g、满足欧Ⅴ标准的超低硫柴油。S-RASSG催化剂级配技术为炼油企业生产满足国Ⅳ和欧Ⅴ标准的超低硫柴油提供了有力的技术支撑。To meet the requirement for the production of Euro-Ⅳ and Euro-Ⅴ clean diesel for refineries,Fushun Research Institute of Petroleum Petrochemicals（FRIPP） has developed FHUDS series catalysts with W-Mo-Ni（Mo-Ni） or Mo-Co as active metal,which have a strong adaptability to different feedstocks.Based on different operating conditions and reaction characteristics of different catalyst beds in running cycle and in consideration of ultra desulfurization mechanisms of different types of catalysts,S-RASSG diesel ultra deep desulfurization technology with different catalyst stack loading has been developed by FRIPP.The commercial application results show that： when S-RASSG catalyst stack technology and its associated FHUDS-2/FHUDS-5 catalysts are applied,the high sulfur feed blended with 60% SRGO and 40% LCO,coker diesel or vacuum tower diesel can be processed to stably produce product diesel with sulfur lower than 50 ppm which meets Guo-Ⅳstandard specifications at reactor inlet pressure of 8.0 MPa,main catalyst LHSV of 1.85~2.25 h-1,and WABT of 350 ℃,etc.The product diesel with less than 10 ppm sulfur,which meets Euro-Ⅴ standard can be produced with feed blended with 70% SRGO,30% vacuum tower diesel and a small quantity of coker diesel under the conditions of reactor inlet pressure of 8.0 MPa,main catalyst LHSV of 1.85 h-1,WABT of 350 ℃,etc.S-RASSG catalyst stack technology has provided a strong technology support for production of Euro-Ⅳ and Euro-Ⅴdiesels for refineries.
