This paper discusses an apparatus for separating gaseous contaminants and particular contaminants, including sticky components, from a dirty hot gaseous stream. It comprises a vessel defining an interior chamber; a walled housing disposed in the vessel for containing a moving bed of coarse particulate material therein, forming an enclosed area between the housing and the vessel; means for moving the bed through the housing; a dividing wall separating the enclosed area into a first section for flow of dirty hot gases therethrough and a second section for flow of cleaned gases therethrough; means for introducing the dirty gaseous stream into the vessel and into the walled housing; means for discharging clean gases from the second section of the enclosed area; a supply of sorbent material disposed in the walled housing, after passage through at least a portion of the moving bed, sufficient to remove gaseous contaminants from the hot gaseous stream. The walled housing having at least one aperture in the walls thereof for flow of dirty gases from the walled housing into the first section of the enclosed area, with substantially no flow of the coarse particulate material therethrough; and hollow, ceramic, barrier filter units.
