Dispersing-type catalyst for hydrocracking of heavy oil and residuum, and a method for the preparation thereof

摘要

This invention discloses a dispersing-type catalyst for catalytic hydrocracking 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 DEG C. under 10-15 MPa of hydrogen pressure, in which the catalyst is added in an amount to provide 150-1500 ppm active metals. The yield of light oil according to the process is more than 70 wt %, substantially without coking.
