ABSTRACT:
A process for reducing the amount of carbon monoxide emitted from a fluidized bed reactor for chlorinating titanium bearing material containing iron oxide comprising (a) feeding coke, titanium bearing material containing iron oxide, and chlorine to the reactor, the chlorine being fed to the reactor below the surface of the fluidized bed, (b) maintaining the feed rate of the materials in step (a) and the conditions of operation of the bed so that the iron oxide is substantially converted to ferrous chloride, and (c) feeding sufficient chlorine to the reactor at or near the surface of the bed to convert the desired amount of carbon monoxide to carbon dioxide.
