  • Thermal decomposition of aluminum chloride hexahydrate
    Patent number: 4402932
    Abstract: Aluminum chloride hexahydrate is thermally decomposed to alumina by sequential treatment in two dense fluidized-bed decomposers, the first decomposer being operated at a temperature of about 200.degree. to 400.degree. C. and the second at a temperature of about 900.degree. to 1100.degree. C. About 90 to 95 percent decomposition is achieved in the first decomposer, with substantially complete decomposition of the remainder in the second decomposer. Fluidization in the first decomposer is preferably achieved by means of recycle of product gases.
