A series of Ni and Ni-Co were maintained on a mixed support of USY (ultrastable Y) zeolite and active aluminum oxide. The catalysts were characterized by means of element analysis, BET and XRD. The characterization results suggested that the active metal components were introduced without changing the microstructure. Then catalytic hydrocracking activity was studied using AATO (distillate of coal tar) in a tubular reactor. AATO conversion was 39.40% and 41.37% using the 10%Ni/USY catalyst and 10%Ni-6%Co/USY catalyst, the hightest total selectivity of benzene and xylol was 67.1% in 10%Ni-10%Co/USY catalyst than others under the reaction conditions studied [T=480°C, P=4.5MPa, LHSV=3.0h-1].
