Abstract
A process for hydrocracking heavy oil which comprises hydrocracking the heavy oil in the presence of a catalyst comprising a support of 10 to 90% by weight of an iron-containing aluminosilicate and 90 to 10% by weight of an inorganic oxide, and at least one metal belonging to Group VIB of the Periodic Table and at least one metal belonging to Group VIII deposited on the support. The iron-containing aluminosilicate has a composition of the formula expressed as oxides: aFe.sub.2 O.sub.3 .multidot.Al.sub.2 O.sub.3 .multidot.bSiO.sub.2 .multidot.nH.sub.2 O wherein n is a real number of 0 to 30, and a and b are real numbers satisfying the following relationships: 15<b<100, 0.005<a/b<0.15; and has an inert iron compound content, (Fe).sub.dep, as calculated by a temperature programmed reduction, of not more than 35% of the total iron content; and when subject to a temperature programmed reduction, Th (.degree.C.), is within the following equation: 850.degree. C..ltoreq.Th.ltoreq.(-300.times.UD+8,300).degree. C. wherein UD is a lattice constant (.ANG.) of the iron-containing aluminosilicate.
