Abstract
A metal chloride generator is provided. The metal chloride generator is a metal chloride centrifugal reactor that can be operated under conditions sufficient to cause metal particles and chlorine in the generator to be brought into contact with one another and react using centrifugal force to form metal chloride. A process for manufacturing titanium dioxide that utilizes the metal chloride generator is also provided.
Claims19
A chloride process for manufacturing titanium dioxide, comprising:
- introducing titanium dioxide ore, a carbon source and chlorine into a chlorinator;
- operating said chlorinator under conditions sufficient to cause titanium dioxide ore, said carbon source and chlorine in said chlorinator to react to form titanium tetrachloride;
- introducing metal particles and chlorine into a metal chloride generator, wherein said metal chloride generator is a metal chloride centrifugal reactor;
- operating said metal chloride generator under conditions sufficient to cause metal particles and chlorine in said generator to be brought into contact with one another and react using centrifugal force to form metal chloride;
- introducing titanium tetrachloride formed in said chlorinator, metal chloride formed in said metal chloride generator and oxygen into an oxidizer;
- operating said oxidizer under conditions sufficient to oxidize titanium tetrachloride and metal chloride in said oxidizer to form titanium dioxide particles having a metal oxide incorporated into their crystalline lattice structure;
- and
- recovering titanium dioxide particles formed in said oxidizer.
