A dual electrolytic cell by molten salt electrolysis apparatus and process of the preparation of pure titanium

a two electrolytic cell by molten salt electrolysis apparatus and process of preparing titanium , which process comprises TiO2 chloride, calcium thermal reduction prepared TiClx? (X = 2,3) and three parts electrolytic reduction prepared TiClx Ti. In the first electrolytic cell the anode to produce TiO2 Cl2 to give TiCl4 chloride electrolytic cell bottom, the cathodic reduction and mass Ca reduction of TiCl4 to step TiClx (x = 2,3), TiClx side communication through the first cell tube into the second electrolytic tank, on the cathode can be reduced to pure titanium, Cl2 simultaneously generated at the anode and recycled to the bottom of the slot 1, continue to participate in the chlorination reaction of TiO2. Advantage of the present invention: TiO2 directly in the electrolytic cell using the cathode chloride for calcium Ca product prepared TiClx thermal reduction, and achieve continuous circulation of electrolyte through the electrolysis process, the double-cell applications, and the chloride TiO2 TiClx separately prepared TiClx electrolytic reduction, the product was extracted titanium is conducive to ensure the purity of titanium, Cl2 turn two generated at the anode to achieve recycling, to further reduce energy consumption and pollution.
