ABSTRACT:
An improved moving bed contacting design is disclosed, which is especially useful for moving bed reforming. A moving catalyst bed is contained in a single, downflowing annular bed. Multiple feed inlet and outlet locations, and baffles on screens containing the catalyst, permit radial flow operation through a single bed of catalyst to simulate several distinct catalyst beds. Some gas may flow up or down, instead of radially to increase or decrease the loading of the catalyst bed.
