Abstract
Chlorination of ilmenite to produce titanium products results in large quantities of byproduct ferric chloride. This finely divided, deliquescent material is extremely corrosive and presents a difficult waste disposal problem. In particular, it is difficult to transfer accurately and reliably for processing in fluidized-bed operations for chlorine recovery. Compacting ferric chloride into hard, dense pellets reduces its tendency to pick up moisture and allows it to be easily fed into oxidation units where it can be converted to iron oxide and recyclable chlorine. Pelletizing also allows the incorporation of promoters such as sodium chloride and fuels such as carbon or metallic iron within the feed pellets. Bench-scale studies in fluidized-bed oxidation reactors are described and discussed. A product gas containing 80 pct chlorine was produced at 800 deg. C in a reactor where pelletized ferric chloride was fed to the bottom of a fluidized bed of iron oxide.
