ABSTRACT:
This invention provides a fixed bed of nonuniformly sized grade catalyst particles for hydrocracking or hydrodesulfurization. The graded particles are arranged with the largest particles in either the upstream or the downstream portion of the bed. In either case, when compared with the conventional bed of uniformly sized particles, the graded bed of this invention shows enhanced hydrocarbon conversion activity for heavy oils over a useful range of conversion. Such catalyst bed is particularly useful in moderate hydrocracking operating at less than 1000 psig (7000 kPa) pressure.
