摘　　要：采用高压加氢裂化装置对以不同分子筛为载体负载了镍金属的A、B、C型3种催化剂进行评价。结果表明,C型催化剂的比表面积和微孔孔容最大,AATO馏分的转化率为39.4%,苯和二甲苯的收率之和为18.5%。对加氢裂化性能较理想的C型催化剂添加钴金属进行性能改善,结果显示金属钴的添加有利于BTX收率的提高,BTX收率为25.9%。The three kinds of A, B, C catalysts for which different molecular sieves carrying Ni are taken as carrier are evaluated with high pressure hydrocracking device. The result indicates that type C catalyst has biggest specific area and pore Volume and AATO distillate conversion rate is 39.4%. The sum of benzol and xylene yields is 18.5%. Co is added to type C catalyst that has more ideal hydroeraeking property, in order to improve property. The result shows that the addition of Co is favorable for BTX yield improvement and BTX yield is 25.9%.
