摘　　要：针对某石化公司焦化汽柴油加氢装置掺炼催化柴油混合原料使得加氢脱硫难度增加,催化剂失活速率加快,催化剂寿命缩短等问题,开发出TH/FHUDS系列加氢催化剂级配技术,并与HPS/FHUDS加氢催化剂的工业应用进行对比。结果表明:与HPS/FHUDS加氢催化剂相比,TH/FHUDS加氢催化剂的加氢捕硅剂装填量减少14.78 t,加氢精制催化剂装填量增加42.27 t;在焦化汽柴油和催化柴油混合进料量为250 t/h,加氢保护反应器入口温度为289℃,氢分压为7.3 MPa,氢油体积比为560,加氢主反应器平均反应温度为364℃的条件下,能够稳定生产含硫量不大于10μg/g的超低硫柴油;后者的加氢脱硫、脱氮活性更高,芳烃饱和能力更强,精制柴油产品的含硫量降低2.7μg/g,含氮量降低42.3μg/g,多环芳烃质量分数降低3.9个百分点,十六烷值提高约2个单位。The TH/FHUDS series hydrogenation catalyst grading technology had been developed to address issues such as increased difficulty in hydrodesulfurization,accelerated catalyst deactivation rate,and shortened catalyst life caused by the blending of catalytic diesel as feedstock in the coking gasoline/diesel hydrogenation unit of a petrochemical company.The technology had been compared with the industrial application of HPS/FHUDS hydrogenation catalysts.The results showed that compared with HPS/FHUDS hydrogenation catalyst,the loading amount of hydrodesilication agent in TH/FHUDS hydrogenation catalyst decreased by 14.78 t,and the loading amount of hydrogenation refining catalyst increased by 42.27 t.Under the conditions of a mixed feed rate of 250 t/h of coking gasoline/diesel and catalytic diesel,an inlet temperature of 289℃for hydrogenation protection reactor,a hydrogen partial pressure of 7.3 MPa,a hydrogen oil volume ratio of 560,and an average reaction temperature of 364℃for the hydrogenation main reactor,production of ultra-low sulfur diesel with a sulfur content not exceeding 10μg/g could be achieved stably.The latter had higher hydrogenation desulfurization and denitrification activity,stronger aromatic saturation ability,and the sulfur content of refined diesel products decreased by 2.7μg/g,the nitrogen content decreased by 42.3μg/g,the polycyclic aromatic hydrocarbon mass fraction decreased by 3.9 percentage points,and cetane number increased by 2 units.
