<p>Thermally splitting hydrate of aluminum chloride to produce aluminum oxide wherein the hydrate is at least partially split by contact with hot gases and hot calcined product in a turbulent zone, transmitting the material from the turbulent zone into a residence zone, recycling a portion of the solids from the residence zone to the turbulent zone in an amount to maintain a desired suspension density while the remainder is passed to a turbulent cooling zone in heat exchange with the fluidizing gas introduced into the turbulent zone.</p> |
