| titleOfInvention | Process for the thermochemical production of titanium |
| abstract | The present invention proposes a method and a device for the thermochemical production of titanium. The process has at least the following process steps: providing gaseous titanium tetrachloride comprising: a) providing a starting material comprising titanium dioxide, b) digesting the starting material in mineral acid to form a solution comprising dissolved titanium (IV), c) precipitating an alkali metal titanium (IV) hexachloride the solution with an alkali metal chloride with the addition of hydrochloric acid or hydrogen chloride, e) heating the alkali metal titanium (IV) hexachloride with the formation of solid alkali metal chloride and gaseous titanium tetrachloride; Reduction of the gaseous titanium tetrachloride to titanium trichloride comprising: f) providing a reducing agent, g) reducing the gaseous titanium tetrachloride with the reducing agent with the release of chlorine to titanium trichloride, the reducing agent being oxidized with the absorption of chlorine, h) recycling the oxidized obtained in process step g) Reducing agent by reduction with the formation of chlorine gas and / or oxygen and providing the recycled reducing agent as reducing agent in method step f); Disproportionation of the titanium trichloride to titanium and titanium tetrachloride comprising: j) disproportionation of the titanium trichloride or the titanium dichloride to titanium and titanium tetrachloride, k) providing the titanium tetrachloride obtained in process step j) and optionally i) as titanium tetrachloride in process step g); and separating the obtained titanium. |
