THERMALDECOMPROSITION OF ALUMINIUM CHLORIDE HYDRATE IN INDIRECT HEATED AND DIRECTLY HEATED REACTORS

摘要

The thermal decomposition of aluminum chloride hydrate in which the preponderant portion of the hydrate is thermally decomposed in an indirectly heated reaction chamber while in a fluidized state with any remainder thermally decomposed in a directly heated rotary furnace and passing the formed aluminum oxide in heat exchange with combustion gases to cool the aluminum oxide and to preheat the combustion gases.
