A DISPERSING-TYPE CATALYST FOR HYDROCRACKING OF HEAVY OIL AND RESIDUUM, THE PREPARATION AND THE USE THEREOF

摘要

This invention discloses a dispersing-type catalyst for catalytichydrocracking ofheavy oil and residuum, the preparation method thereof and a suspension bedhydrocracking process for hydrocracking of heavy oil and residuum using saidcatalyst. Said catalyst comprises 2 to 15 wt% Mo, 0.1 to 2 wt% Ni and 0.1-3wt%P. The preparation method comprises dissolving oxides or salts of metals suchasMo, Ni in water. The process comprises mixing the heavy oil and residuumfeedstock with the catalyst, heating the mixture and introducing the mixtureinto asuspension bed reactor, performing the hydrocracking reaction at 380-460 ~under10-15MPa of hydrogen pressure, in which the catalyst is added in an amountto provide 150-1500ppm active metals. The yield of light oil according to theprocess is more than 70 wt%, substantially without coking.
