ABSTRACT:
A process for the desulfurization and demetalation of a nickel and sulfur containing heavy hydrocarbon charge stock comprises: admixing the feed with hydrogen; reacting the admixture in a reaction zone containing desulfurization catalyst at desulfurization conditions; injecting water into the reaction zone at H.sub.2 O/H.sub.2 molar ratios of about 0.05 to 0.5; separating and recycling both hydrogen and water from the reactor effluent; and recovering the substantially sulfur and nickel free product.
