Abstract: For the new change of refining trend all over the world, through innovating the two-step pore-making technology of Y molecular sieve, FRIPP invent the acid reconstruction technology to control the migration of Y molecular sieve sodium cage, and creat high efficient DMY molecular sieve. Using DMY molecular sieve as cracking component, a new generation of naphtha selective hydrocracking catalyst FC-82 was developed. Compared with FC-52, the bulk density of catalyst decreased by 13%. Under the same yield of tail oil, the selectivity of heavy naphtha increased by 1.7~2.0 percentage points and the BMCI of the tail oil was the same. FC-82 can be used to produce heavy naphtha and ethylene cracking raw materials, and get the maximum amounts of heavy naphtha under the same yield of tail oil.

摘要： 针对国内外炼油形势的新变化，中国石油化工股份有限公司大连石油化工研究院创新了Y型分子筛的“两步造孔技术”，发明了控制Y型分子筛方钠石笼迁移的“酸性位重构技术”，创造出双介孔结构的高效DMY（Double Mesopore Y）分子筛，并研制了新一代轻油型加氢裂化催化剂FC-82。与FC-52催化剂相比，FC-82催化剂的堆积密度降低了13%；在相同转化率下，重石脑油收率明显增加，两次评价试验分别提高了2.0，1.7百分点，尾油芳烃指数（BMCI值）基本相当。使用FC-82催化剂，可以兼顾重石脑油和乙烯裂解原料的生产，在高转化率试验条件下可实现最大量生产重石脑油。
