Abstract
A catalytic reactor system for effecting the contact of a reactant stream with catalyst particles that are movable by gravity flow through the system, which comprises in combination: (a) a vertically elongated confined reaction chamber; (b) a catalyst loading chamber having a fixed volume located outside of and generally overhead of the reaction chamber whereby fresh catalyst particles gravitationally flow downward into the chamber; (c) concentrically spaced apart wall members which provide an annular-form catalyst-retaining section that is spaced inwardly from the wall of the reaction chamber to additionally provide a manifold space around the section and a cylindrical center pipe volume, the wall members having a perforate screen lower end and an imperforate upper end wherein the imperforate upper end defines a portion of the annular-form catalyst-retaining section having a volume of greater than about 100% of the catalyst loading chamber; (d) an imperforate cover means over the annular-form catalyst-retaining section; (e) catalyst transfer means which connects a lower portion of the catalyst loading chamber to the top of the annular-form catalyst-retaining section; (f) catalyst outlet means which connects the annular-form catalyst-retaining section to the lower portion of the reaction chamber; (g) a reactant stream inlet means in communication with the reaction chamber and passageway means to the annular space around the annular-form catalyst-retaining section; (h) a reactant stream outlet means in communication with the reaction chamber and passageway means from the cylindrical center pipe volume within the annular-form catalyst-retaining section to the outlet means; and (i) a plurality of uniformly spaced apart catalyst outlet means provided from the annular-form catalyst-retaining section and from the reaction chamber.
