Abstract

A multi-step process for catalytically reforming a hydrocarbon feedstock, comprising the steps of: (a) introducing, at least periodically, fresh or regenerated catalyst particles at the upper end of a first reaction zone, by the that the catalyst particles can be displaced by gravity flow, at least periodically removing particles of activated catalyst from the lower end of said first reaction zone, and reacting said charge material, in the absence of added hydrogen, in said first reaction zone, under conditions of catalytic reforming; (b) introducing, at least periodically, fresh or regenerated catalyst particles at the upper end of a stacked reactor system containing a plurality of reaction zones having a common vertical axis, and whereby the catalyst particles they can be displaced by gravity flow, removing, at least periodically, catalyst particles deactivated from the lower end of said system, and introducing the reaction effluent product from said first reaction zone into the uppermost reaction zone of said reactor system stacked, and under conditions of catalytic reformation; (c) further reacting the resulting higher reaction effluent product, under catalytic reforming conditions, in a lower reaction zone of said stacked reactor system; and (d) recovering a catalytic, normally liquid, reforming product from the effluent removed from the lowermost reaction zone of said stacked reactor system.
