Abstract: The present invention relates to a highly active midbarrel hydrocracking catalyst and a process for the preparation thereof. The support of the catalyst comprises a modified zeolite-Y, a modified zeolite-&bgr;, alumina, etc. The composite of the modified zeolite-Y and zeolite-&bgr; exhibits a good synergistically catalytic effect. The catalyst prepared by supporting Group VIB and/or Group VIII metal components is useful in the hydrocacking of heavy oils with high content of sulfur and nitrogen to produce high quality middle distillates with maximum output. The activity of and selectivity to middle distillates of the catalyst are remarkably raised simultaneously. Moreover, the solidifying point of the produced diesel is remarkably lowered.
