Process for hydrocracking of heavy oils with iron containing aluminosilicates

摘要

The invention provides a process for hydrocracking heavy oils in the presence of a catalyst comprising a carrier and metals belonging to the Groups VIB and VIII of the Periodic Table. The carrier consists of from 20 to 80% by weight of iron-containing aluminosilicate and from 80 to 20% by weight of an inorganic oxide. The iron-containing aluminosilicate is prepared by treating steam-treated crystalline aluminosilicate with an aqueous iron salt solution at a pH of 1.5 or less. The molybdenum/iron-containing aluminosilicate can be used in place of the iron-containing aluminosilicate. According to the process of the present invention, the yield of an intermediate fraction can be increased.
