Abstract:
This disclosure relates to a fluidized bed reaction system and method for continuous production of titanium tetrachloride from titanium-bearing materials containing high concentrations of alkaline earth metal impurities. Agglomerated heavy particles in a reaction are taken out continuously from a chlorination reactor without clogging and stopping. The reactors and related methods disclosed apply to the chlorination of titanium slag containing high content of alkaline earth metal oxides of up to 15% by weight.

Claim (Index 1):
A fluidized bed reaction system comprising:\n a reactor base comprising a center and a rim, wherein the center is recessed relative to the rim; at least one reactor wall defining, together with the reactor base, an enclosed space comprising a collection zone and a reaction zone, wherein the collection zone comprises a space within the recessed center of the reactor base, wherein the reaction zone comprises a space above the center and the rim of the reactor base such that the reaction zone is above the collection zone; a plurality of center nozzles formed through the recessed center of the reactor base and configured to supply fluidizing gas to the reaction zone via the collection zone; a plurality of rim nozzles formed through the rim of the reactor base and configured to supply fluidizing gas directly to the reaction zone; a gas flow control configured to control flow of the fluidizing gas to the plurality of center nozzles and to the plurality of rim nozzles such that a linear fluidizing velocity of the fluidizing gas supplied through the plurality of center nozzles is substantially lower than a linear fluidizing velocity of the fluidizing gas supplied through the plurality of rim nozzles.
