Abstract
An improved radial flow moving bed reactor, or other type of fluid-solid contacting vessel, in which stagnant catalyst volumes are reduced. The improvement results from the placement of a plurality of catalyst collection scoops or a single discoid cover plate just above the catalyst withdrawal conduits in a manner which directs the removal of catalyst through an annular opening adjacent the inner catalyst retention screen.
