ABSTRACT:
A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity flow. Dissimilar catalyst particles are utilized in the reactor systems which share a common regenerating tower through which the catalyst particles are downwardly movable via gravity flow and in which the catalyst particles are regenerated in segregated fashion. Dissimilarity of the catalyst particles stems from a difference in activity, stability and selectivity characteristics. In turn, this difference may be attributed either to physical, or chemical distinctions between the two composites, or both.
