Abstract The present invention discloses one kind of hydrocracking catalyst for hydrogenating inferior heavy oil and residual oil in suspension bed. The catalyst features that it contains complex formed by heterocyclic sulfo compound and Fe, Co, Ni, Mo, W and other metal and the heterocyclic ring contains hetero atom, such as S, N and O. The catalyst can be dissolved homogeneously in the heavy oil and residual oil, and in the presence of hydrogen, the inferior heavy oil and residual oil containing the catalyst may be hydrocracking into light product. The process has low catalyst cost, high light product yield and low coke rate.
