| titleOfInvention | Process for the production of titanium tetrachloride |
| abstract | 1506691 Titanium tetrachloride ISHIHARA SANGYO KAISHA Ltd 26 March 1976 [28 March 1975] 12307/76 Heading C1A TiCl 4 is continuously produced in a dilute phase fluidized bed by feeding a titaniferous material having a particle size of 400-150 mesh (Tyler standard) as a median value, a solid carbonaceous substance having a median particle size at least three times that of the titaniferous material and Cl 2 -containing gas to a reactor which has a vertical solid suspension zone which is wider at the top than at the bottom, the ratio of the height of the zone to the diameter at its lowest part being at least 10:1 and the ratio of the cross sectional areas of its uppermost and lowest part being 1À2-10:1; controlling the amounts of reactants such that the maximum value of the superficial linear velocity of the gas is 1-10m/sec, the solids concentration is 10-200kg/m<SP>3</SP> and the concentration of solid carbonaceous substance in the solids is 70-99%, maintaining a fluidized bed of the carbonaceous substance in which the titaniferous is chlorinated at 900-1400‹C. while it ascends entrained in the gas flow and removing the reaction gases from the upper part of the reactor and separating the gas into a chloride gas containing TiCl 4 and unreacted solid substances, which are preferably recycled. The titaniferous material may be rutile or ilmenite ore, titanium concentrates such as slag, beneficiated ores or titanium residue recovered from the production of TiO 2 pigments. The carbonaceous substance may be coke, anthracite or charcoal and preferably has a particle size of 60-14 mesh. In the preferred embodiment, a titaniferous material and solid carbonaceous substance are introduced into the reactor through a feed pipe 13 and/or upper feed pipe 14. Cl 2 -containing gas is introduced through pipe 5 and flows upwardly through the reactor. The exit gases are passed through a cyclone 8 and the solids recovered from the gas are recycled to the lower part of the reactor. The separated gas is treated for separation of TiCl 4 after passage through a further cyclone 9. |
