Title: Reactor design for smaller batch transfers of catalyst

Abstract: A moving bed of catalyst loses activity as it moves through the reactor. Creating multiple passes for the process fluid moving across a catalyst bed, increases the utilization of the catalyst and creates a pseudo-counter current flow of catalyst and process fluid. The flow improves the temperature profile of the bed and allows higher temperature fluid contacting the less active catalyst.
