Abstract
In an ebullated bed process, a residual hydrocarbon oil and a hydrogen containing gas is passed upwardly through an ebullated bed of catalyst in a hydrocracking zone at a temperature in the range of 650.degree. F. to 950.degree. F. and pressure of 1000 psia to 5000 psia. The hydrogen containing gas comprises hydrogen sulfide in an amount to maintain the sulfur content of the oil in the hydrocracking zone at 2 wt % to 10 wt %. A hydrocracked oil is recovered characterized by having a reduced sediment content.
