ABSTRACT:
The operation of an ebullated-bed, liquid-phase hydrogenation process for the hydrocracking of a residuum hydrocarbon in the presence of a particulate catalyst is improved by operating under conditions such that there is a greater laydown of carbon on the catalyst than permitted in conventional operation of an ebullated-bed system which is followed by catalyst regeneration in the presence of steam and air and recycle of such regenerated catalyst to the reactor.
