Abstract

Titanium dioxide is produced by feeding titanium tetrachloride with an oxygen-containing gas to a fluidized bed of inert material having a particle size of 40 to 1000m and having a nature such that on fluidizing with air at 1000 DEG C. for 100 hours at five times the minimum fluidizing velocity, the entrained fines constitute less than 5 per cent of the material originally present. Suitable materials are silica, alumina, zircon and rutile, which may have been previously chlorinated to remove impurities. The tetrachloride may be fed admixed with the oxygen-containing gas or as a jet of gas or liquid to the perforated plate on which the bed rests or to a point in the fluidized bed. If desired fuel gases such as carbon monoxide may be mixed with the reactants or separately fed to the bed to supply heat, or heat may be supplied from an external source. The temperature of the bed may be from 700-1200 DEG C., preferably 800-950 DEG C. for anastase production and 800-1100 DEG C. for rutile production. The tetrachloride/oxygen ratio may be from 1 : 0.2 to 1 : 5. Specification 724,193 is referred to.
