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: Regarding the prolific reforming raw material technology for the high nitrogen and naphthenic distillate hydrocracking,China National Offshore Oil Corporation (CNOOC) Tianjin Chemical Research & Design Institute Limited Corporation,by modifying the silica alumina ratio of the molecular sieves,the molecular sieves content of the supporter and the metal content of the catalysts,has successfully developed THHC-I hydrocracking catalyst,after pilot preparation,industrial amplification,and industrial production. The THHC-I hydrocracking catalysts for industrial production show the same physical-chemical properties and catalytic performance as the hydrocracking catalysts for pilot preparation and industrial amplification. The 1500h assessment results of the catalyst pilot test for Zhoushan coking heavy distillates show that the conversion of distillate with boiling point>345℃ is 75.8% and the liquid yield of naphtha with boiling point<170℃ is 42.7%. The sulfur and nitrogen content of naphtha are 1μg/g,0.6μg/g respectively. The sulfur and nitrogen content of diesel are 5μg/g,3μg/g respectively. The assessment results also indicate that THHC-I hydrocracking catalysts show excellent cracking activity,selectivity and stability. THHC-I catalyst has been accomplished 30 tons of production,and successfully applied in the coker heavy distillate hydrocracking using the prolific reforming raw material technology in CNOOC Zhoushan Petrochemical.
