ABSTRACT:
Thermal decomposition of aluminum chloride hydrate in a fluidized bed reactor in which the concentration of solids diminishes from the bottom upwards, the improvement wherein most of the hydrogen chloride is removed from the hydrate by direct heat and the largely decomposed aluminum chloride is fed into a calcining reactor and from the calcining reactor to a residence time reactor fluidized at low gas velocity, recycling solids from the residence reactor to the calcining reactor in an amount to adjust the suspension density and feeding the remainder to a cooler after sufficient time in the residence reactor.
