摘　　要：针对一段串联加氢裂化工艺，进行了新型化工原料型加氢裂化催化剂的研发工作．200mL固定床加氢评价结果表明：以大庆VGO为原料，在控制原料（〉177℃）馏分油转化率为63％的转化率条件下，加氢裂化轻石脑油（〈65℃）收率为15．1％，可作为乙烯裂解原料或清洁汽油调和组分；重石脑油（65～177℃）收率为48．3％，芳潜为49％，是优质的催化重整原料；柴油（177～320℃）硫含量低于15ug／g，芳烃含量低于5％，可作为清洁柴油调和组分；尾油（〉320℃）收率为11．1％，BMCI值为5，是优质乙烯裂解原料．2000h的活性稳定性试验表明，研制的催化剂具有良好的活性稳定性，能够满足工业装置长周期运行的要求．A novel hydrocracking catalyst was developed for producing chemical materials with reactors in series process. Evaluation of catalytic performance of the hydrocracking catalyst was carried out on a 200 mL fixed-bed hydrogenation unit. The results showed that under the 63% conversion of feedstock distillate （ 〉 177℃） using Daqing VGO as feedstocks, the yield of light naphtha （ 〈65℃） was 15.1% , which can be cracking raw material for ethylene production or blending components of clean gasoline; the yield of heavy naphtha （65 - 177℃ ） was 48.3% with potential aromaties of 49% , which can be high quality cracking raw material for ethylene; diesel oil （177-320 ℃ ） whose sulfur content is less than 15ug/g and aromatics content is less than 5Ф% ,which can be blending components of clean diesel ; the yield of tail oil （ 〉 320℃ ） was 11.1% with low BMCI value of 5, which can be cracking raw material for ethylene production. 2 000 h of activity and stability tests show that the developed catalyst has good activity and stability, which can meet long-term operation of plant requirements.
