新型介孔分子筛加氢裂化催化剂的研制

研究了一种最大量生产中间馏分油的新型介孔分子筛加氢裂化催化剂，200 mL一段串联加氢装置评价结果表明，在控制原料＞350 ℃馏分油75%的高转化率条件下，C_⁺⁵液收98.6%，加氢裂化生成油中最大量柴油馏分收率为67.36%，中油选择性79.2%，能满足工业装置最大量生产中间馏分油的需要。重石脑油芳潜收率为41.16%，尾油BMCI值5.9，是理想的重整原料和蒸汽裂解制乙烯原料。

Development of a new mesoporous hydrocracking catalyst

A new mesoporous hydrocracking catalyst for maximum middle distillate production was developed. The test results for the catalyst on a 200 mL single stage hydrocracking unit showed that C⁺⁵ liquid yield of 98.6wt%, diesel distillate yield of 67.36wt%, and selectivity to middle distillates of 79.2% were obtained under controlling conversion of ＞350 ℃ distillate at 75%, which met the requirement on maximum middle distillate output on the unit. Meanwhile, the heavy naphtha, with high aromatic potentiality (41.16%), and the tail oil, with low BMCI value(5.9), were perfect reforming and steam cracking feedstock.
