Abstract
A hydrocracking catalyst for heavy hydrocarbon oils comprising a metallic element of the VIb Group and a metallic element of the VIII Group supported on a carrier containing a novel faujasite aluminosilicate which absorbs infrared in a frequency region of 3740.+-.10 cm.sup.-1 in an absorption percentage A of at least 20% and absorbs infrared in a frequency region of 3560.+-.10 cm.sup.-1 in an absorption percentage B of at least 5%, the ratio of A/B being at least 2, has a specific surface area of at least 650 m.sup.2 /g, has a framework SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of from 20 to 50, and has a lattice constant of from 24.15 to 24.50 .ANG.. The novel faujasite aluminosilicate is produced by treating a faujasite zeolite with an acid.
