Abstract
An improved process for the production of aluminum chloride from coked alumina and chlorine comprises providing a bed of coked alumina in a reaction vessel and introducing gaseous chlorine thereto in an amount sufficient to fluidize the bed, at least a portion of the vessel having a nitride-based refractory lining especially adjacent and bounding the lower part of the fluidized bed. Aluminum chloride formed is recovered as a gaseous effluent emmanating from the bed.
