Abstract
An apparatus is presented for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with openings disposed within the partitions. The openings are covered by louvers that extend above the edges of the openings to prevent solid particles from spilling through inlet openings, and the design prevents the loss of particles through the openings during cooldown of the apparatus.
