REACTOR MULTI-PASS GRIDS FOR IMPROVED CATALYST HYDRODYNAMICS

摘要

A process and device for the flow of catalyst in a reactor is presented. The device includes a series of grids within a reactor vessel, where each grid includes small openings for the passage of gas and some catalyst particles, and larger openings for the more continuous passage of catalyst. The grids span horizontally across the vessel, and are spaced vertically apart to provide for the flow of catalyst down through the reactor.
