Abstract
A hydrocracking catalyst composition comprising metals of Group VIb and Group VIII deposited on a carrier material consisting of Y-zeolite and one or more members of the group consisting of alumina/zinc oxide, alumina/boria and alumina/silica/magnesia, the greater part of the pores of said composition having a diameter of 70-110 .ANG. even when measured by nitrogen adsorption method or by means of a porosimeter under pressure. The catalyst composition having the pores as mentioned above is made by using, as an alumina component of the carrier material, an alumina cake obtained from an amorphous alumina hydrate slurry containing a pseudoboehmite having a crystal size grown in the range of 40 to 80 .ANG..
