Pilot Scale Experiments on the Oxidation of $TiCl_4$

ABSTRACT

Pilot-scale experiments on the oxidation of TiCl4 to produce TiO2 were carried out in a verical reactor of 20cm in inside diameter and 140cm in length ; LPG burning was used as a heating means to maintain the reaciton temperature. The effects of reaction temperature and excess oxygen content on the conversion of TiCl4 and on the particle size of produced TiO2 were investigated. The ranges of operating conditions varied were 900 to TiO2 was 0.45-0.57${mu}{textrm}{m}$, TiCl4 conversion was 82-96%, the rutile content was 33-57% and the contents of impurities were 0.03% of Fe, 0.03% of SiO2 and 62ppm of Cl. These experimental results were compared with those of other investigators.
