摘　　要：为配合柴油产品质量升级至满足国Ⅴ排放标准,中国海油惠州炼化分公司焦化汽柴油加氢装置选择中国石化抚顺石油化工研究院研制的新一代柴油超深度加氢脱硫催化剂FHUDS-6替换部分FH-40C催化剂进行生产。在110%负荷(269t/h)下对装置进行了标定。结果表明,采用FH-40C/FHUDS-6催化剂组合工艺处理焦化汽油、柴油和直馏柴油混合进料(平均硫质量分数为1 923μg/g)时,在反应器入口氢分压7.6 MPa、反应器入口氢油体积比523、精制剂床层平均温度365℃、体积空速1.931h-1的条件下,精制柴油产品的平均硫质量分数为5.2μg/g、十六烷值为54.57,标定期间平均脱硫率达到99.786%,说明FHUDS-6催化剂具有优异的超深度加氢脱硫性能,并且能够大幅提高柴油产品的十六烷值。精制柴油产品质量能够满足国Ⅴ排放标准要求。In order to meet the requirements of producing phase V national standard diesel, part of FH-40C hydrotreating catalyst in Huizhou Refining ＆ Petrochemicals Co. coker gasoline/diesel hydrotreating unit was replaced with a new generation of diesel deep hydrodesulphurization catalyst FHUDS- 6 developed by SINOPEC Fushun Research Institute of Petroleum and Petrochemicals. The calibration was carried out at 110% load （269 t/h）, and the results show that the catalyst combination of FH-40C/ FHUDS-6 can produce refined diesel （the average sulfur content of 5.2 μg/g, the cetane number of 54.57） with a mixed feed of coker gasoline/diesel and straight run diesel （the average sulfur content of 1 923 μg/g） at reaction conditions of 7.7 MPa in cold high pressure separator, average temperature of 365 ℃, LHSV of 1. 931 h^-1 and the ratio of hydrogen to oil of 523. The desulfurization rate reaches 99. 786%, indicating the excellent performance in deep hydrodesulphurization and cetane number improvement of FHUDS-6 catalyst. The quality of refined diesel can meet the requirements of national phase V standard for diesel product.
