This invention discloses a dispersing-type catalyst for catalytic hydrocring of heavy oil and residuum, the preparation method thereof and a suspension bed hydrocracking process for hydrocracking of heavy oil and residuum using said catalyst. Said catalyst comprises 2 to 15 wt % Mo, 0.1 to 2 wt % Ni and 0.1-3 wt % P. The preparation method comprises dissolving oxides or salts of metals such as Mo, Ni in water. The process comprises mixing the heavy oil and residuum feedstock with the catalyst, heating the mixture and introducing the mixture into a suspension bed reactor, performing the hydrocracking reaction at 380-460.degree. C. under 10-15 MPa of hydrogen pressure, in which the catalyst is added in an amount to provide 150-150O ppm active metals. The yield of light oil according to the process is more than 70 wt %, substantially without coking.
