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 2):
A method of producing titanium tetrachloride, the method comprising:\n introducing TiO 2 -containing slag into a reaction zone of a reactor; supplying fluidizing gas comprising chlorine gas to the reaction zone to cause the following reaction within the reaction vessel:\n TiO 2 +2Cl 2 +C\u2192TiCl 4 +CO/CO 2 , \n wherein the fluidizing gas is supplied via center nozzles formed through a central portion of a reactor base and further via rim nozzles formed through a rim of the reactor base that surrounds the central portion, wherein the fluidizing gas supplied via the central nozzles is supplied at a first linear fluidizing velocity whereas the fluidizing gas supplied via the rim nozzles is supplied at a second linear fluidizing velocity that is higher than the first linear fluidizing velocity.
