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.
Claims30
A metal chloride generator, comprising:
- a reactor housing, said reactor housing including an inside surface, an outside surface, a top portion, a bottom portion, a sidewall connecting said top portion and said bottom portion together, and an interior;
- a cylindrical reaction chamber positioned within said interior of said reactor housing, said reaction chamber including an inside surface, an outside surface, a top, a bottom, a cylindrical side wall connecting said top and said bottom together and an interior, said interior of said reaction chamber having a top half and a bottom half;
- a reactant inlet conduit extending through said sidewall of said reactor housing and said sidewall of said reaction chamber and including an inside surface, an outside surface and an interior, said reactant inlet conduit also including a first opening for receiving at least one reaction component from a location outside of said reactor housing and a second opening for discharging said reaction component into said reaction chamber, said second opening of said reactant inlet conduit being flush with said inside surface of said cylindrical sidewall of said reaction chamber and opening into said interior of said reaction chamber;
- and
- a reaction product outlet conduit extending through said top of said reaction chamber and said top of said reactor housing and including an inside surface, an outside surface and an interior, said reaction product outlet conduit also including a first opening for receiving at least one reaction product from said interior of said reaction chamber and a second opening for discharging said reaction product to a location outside of said reactor housing.

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.
