The deep hydrofining catalyst FHUDS-6 was applied in a 4. 1 Mt/a diesel hydrofining unit firstly, and the operation data of performance test in full capacity was analyzed. Results show that using a feedstock with 11% FCC diesel fraction, under the process conditions of an average catalyst bed temperature of 352℃ . a space velocity of 2. 53 h-1, a hydrogen partial pressure of 6. 15 MPa and hydrogen to oil volume ratio of 254. 3, FHUDS-6 catalyst exhibits high hydro-desulfurization activity and hydro-upgrading activity, the sulfur removal rate researches 98. 02% and the cetane number of treated diesel fuel increases by 5. 7 units. The quality of the obtained diesel product can meet the requirements of National Emission Standard III for diesel fuel.%介绍柴油超深度加氢脱硫催化剂FHUDS-6在国内某大型炼油厂4.1 Mt/a柴油加氢装置上的首次工业应用情况,并对使用该催化剂的满负荷标定数据进行分析.结果表明,在催化裂化柴油比例高达11％、床层平均反应温度352℃、空速2.53 h-1、氢分压6.15 MPa、氢油体积比254.3的工况下,FHUDS-6催化剂具有较高的脱硫、改质活性,十六烷值提高幅度达5.7个单位,脱硫率达98.02％,精制柴油产品质量可以满足国Ⅲ柴油排放标准要求.
