Abstract
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.
