SUPPRESSING SEDIMENT FORMATION IN AN EBULLATED BED PROCESS (D#79,105-F) ABSTRACT OF THE DISCLOSURE 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°F to 950°F and pressure of 1000 psia to 5000 psia. FCCU catalyst fines are added to the ebullated bed in an amount of 15 wt% to 21 wt% of total catalyst comprising hydrocracking catalyst and fines. A hydrocracked oil is recovered characterized by having a reduced sediment content. RAM gh:EX7L/33
