Abstract:

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 hydrocracking 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%.
