| titleOfInvention | Method for the production of titanium dioxide by oxygenating titanium tetrachloride |
| abstract | The invention relates to the production of titanium dioxide by oxygenating titanium tetrachloride and then cooling the titanium dioxide particle-gas mixture while adding scouring particles in a cooling section, the gas-particle flow being made to rotate. According to the invention, the titanium tetrachloride is introduced into the axial oxygen-containing flow on the cross-sectional plane of the tubular reactor, but not in the radial direction. The flow velocity of the oxygen-containing gas exceeds 20 m/s, particularly reaching at least 40 m/s. The method according to the invention makes it possible to effectively remove accumulated TiO<SUB>2</SUB> from the internal wall and the cooling section of the tubular reactor, thus increasing the cooling performance, and produce a TiO<SUB>2</SUB> pigment which has a narrow grain size distribution. |
