Abstract: Construction for a fluidized bed reaction chamber for the chlorination of alumina bearing material including means for effecting the introduction of a central reactant gas stream through a centrally disposed porous gas distribution body and a perimetrically confining reactant gas stream through perimetrically disposed direct flow nozzle system serving as a flowing boundary curtain adjacent a carbon wall backed by compacted high density alumina to minimize undesired flow of reactant chlorine gas through the reaction chamber walls.
