ABSTRACT:
A reactor has a reactor shell having an internal cavity. Within the reactor shell is an inlet means, which is connected to the internal cavity to afford passage of material into the cavity. Within the bottom of the reactor shell is an outlet means, which is connected to the internal cavity to afford passage of material out of the cavity. A porous scallop means lines a lower portion of the internal surface of the internal cavity, and a cover means rests upon the top of the porous scallop means. A porous, vertical, hollow centerpipe fits within the internal cavity, and below the cover means, to form an annulus between the porous scallop means and the centerpipe. The bottom of that centerpipe rests on a ledge within the outlet means, to block access of flow of solids from the annulus. A blocking sleeve is within the reactor shell for preventing the flow of solids from the annulus to the outlet means even if the centerpipe ratchets upward from the outlet means. The blocking sleeve has an upper band of the blocking sleeve that fits within the bottom end of the centerpipe, a ledge plate having a hole in the plate, wherein the plate is attached to the bottom of the upper band so that the hole of the plate is completely within the diameter of the band, and a lower band attached to the bottom of the ledge plate. The ledge plate rests on the ledge within the outlet means.
