【摘要】：针对高氮、环烷基特性的馏分油多产重整原料加氢裂化工艺,本文通过改性Y分子筛硅铝比、载体中分子筛含量与催化剂中Ni-Mo金属含量的优化,经过中试制备、工业放大与工业化生产,成功地开发出THHC-I加氢裂化催化剂。工业生产THHC-I加氢裂化的物理化学性质与催化剂性能及中试制备、工业放大的催化剂相当,催化剂对舟山焦化重馏分油的1500h中试评价结果为:345℃馏分转化率75.8%,170℃石脑油收率42.7%,石脑油中硫含量为1μg/g,氮含量为0.6μg/g,柴油中硫含量为5μg/g,氮含量为3μg/g。表明THHC-I加氢裂化对焦化重馏分油具有优异的加氢裂化活性、轻油选择性与稳定性。该催化剂完成30t的生产,并成功应用于舟山石化焦化重馏分油加氢裂化多产重整原料工艺中。
[Abstract]:In view of the hydrocracking process of reforming feedstock with high nitrogen and naphthenic characteristics, the content of molecular sieve in support and the content of Ni-Mo in catalyst were optimized by modifying the Si / Al ratio of Y molecular sieve, and were prepared by pilot-scale test. THHC-I hydrocracking catalyst was successfully developed by commercial scale-up and commercial production. The physical and chemical properties of commercial production of THHC-I hydrocracking are similar to those of catalyst performance and pilot-scale preparation. The results of pilot-scale evaluation of catalyst for heavy distillate oil from coking in Zhoushan for 1500 h show that the conversion of fractions at 345 鈩，
