ABSTRACT:
A method of hydrotreatment of heavy hydrocarbon oil in the presence of catalysts which comprises hydrodemetallizing and hydrocracking the heavy hydrocarbon oil successively and thereafter hydrodesulfurizing and hydrodenitrogenating the treated heavy hydrocarbon oil. The hydrocracking is carried out in the presence of a catalyst comprising at least one metal or metal compound of the group VIA or the group VIII of the Periodic Table supported on a carrier comprising 10 to 90 weight % of an iron-containing aluminosilicate and 90 to 10 weight % of an inorganic oxide. Other methods of treatment of heavy hydrocarbon oil comprise the hydrotreatment in conjunction with fluid catalytic cracking and/or thermal hydrocracking. The methods provide a naphtha fraction, a kerosene fraction and a gas oil fraction which can be obtained from the heavy hydrocarbon oil efficiently with high yield.
