Abstract:
1. An apparatus for supporting a granular solid in a cross-flow system, comprising: A) an inner surface forming a cylindrical structure and being an inlet partition having inlet apertures defined therein, wherein each inlet aperture has a lower edge and an upper edge; and B) a plurality of inlet louvers arranged vertically on the inlet partition, wherein each inlet louver has an upper edge and a lower edge, and each inlet louver upper edge is attached to the inlet partition at a position above an inlet aperture and extends into a particle retention volume at an angle, θ, of about 1 to about 85 degrees and each inlet louver lower edge extends to at least the lower edge of the inlet aperture; wherein each inlet louver, independently, encircles the inlet partition; and C) an outer surface forming a cylindrical structure, being an outlet partition, and not having a louver arranged on the outlet partition and wherein said apparatus further comprises inlet vanes, where the inlet partition has a particle side and a gas side, and where the inlet vanes have an upper edge and a lower edge, and where the inlet vane lower edges are affixed to the inlet partition on the gas side at the inlet partition aperture lower edges.
