Abstract

A process and device for the regeneration of catalyst is presented. The device includes a series of grids within a regeneration vessel where each grid includes small openings for the passage of gas and larger openings for the passage of catalyst. The grids span horizontally across the vessel and are spaced vertically apart to create a flow of catalyst down through the regenerator.
