摘　　要：对β分子筛结构特点进行介绍，在200mL小型加氢实验装置上考察β分子筛催化剂的加氢裂化性能，并与Y型分子筛和无定形硅铝催化剂的性能进行对比。结果表明：在相同工艺条件下，与Y型分子筛和无定形硅铝催化剂相比，β分子筛加氢裂化催化剂的中间馏分油选择性提高2．0百分点以上，柴油凝点降低4～12℃。β分子筛在加氢裂化反应中表现出异构性能好、裂化活性高、中间馏分油选择性好、产品质量好、抗氮能力强等特点，可应用于最大量生产中间馏分油的加氢裂化催化剂。A brief introduction of the characteristics of zeolite β structure was presented. The hydrocracking performance of catalyst containing zeolite β was studied on a 200 mL hydrocracking device,and compared with catalyst containing zeolite Y and amorphous silicaalumina catalyst. Results show that under the same process conditions, catalysts containing zeolite β exhibit better catalytic performance during hydrocracking than the others, the selectivity of middle distillates is more than two percentage points higher,the setting point of diesel fractions is 4-12 ℃ lower,as well as good isomerization property,high cracking activity and strong nitrogen tolerance, which indicates that hydrocracking catalyst containing zeolite β can be used for maximizing middle distillates production.
