| titleOfInvention | METHOD AND APPARATUS FOR PRODUCING TITANIUM DIOXIDE |
| abstract | The present invention relates to a method and a reactor (10) for producing titanium dioxide by reacting titanium tetrachloride vapor with oxygen. In the method of the present invention, oxygen is injected into the reactor at two or more points, i.e., the first oxidizing gas injection assembly 12 and the second oxidizing gas injecting assembly 26. The temperature of the oxygen injected into the second oxidizing gas injection assembly 26 in the reactor is equal to, greater than or less than the temperature injected in the first oxidizing gas injection assembly 12. A second oxidizing gas injection assembly 26 may be disposed after or before all of the titanium tetrachloride has been injected into the reactor 10. Titanium tetrachloride is injected into the reactor 10 through the first titanium tetrachloride injection assembly 20 at a relatively low temperature of about 427 ° C or less. The reaction temperature in the reactor 10 is at least about 700 ° C. Optionally, a second titanium tetrachloride, which is additionally added in the second titanium tetrachloride injection assembly 34, may be injected into the reactor 10. |
