| titleOfInvention | Method for distilling and separating vanadium tetrachloride and method for recovering vanadium from spent catalyst |
| abstract | (57) [Summary] [PROBLEMS] To establish a chlorination treatment method for a spent catalyst so that high-purity vanadium tetrachloride can be recovered from a spent catalyst at a high recovery rate, and from a reaction product obtained from the spent catalyst. A method for separating vanadium tetrachloride is provided. SOLUTION: This vanadium recovery method is a method of recovering vanadium from a spent catalyst containing vanadium and sulfur. Without subjecting the spent catalyst to roasting treatment, the waste catalyst is chlorinated with a chlorinating agent without chlorinating the catalyst carrier and the catalyst-carrying metal at a temperature in the range of 100 ° C. to 350 ° C. at a pressure of at least atmospheric pressure or higher. And a chlorination step of producing a mixed vapor of vanadium tetrachloride and sulfur dichloride in the reactor 12. Next, a step of cooling the mixed vapor of vanadium tetrachloride and sulfur dichloride to condense it into a mixed liquid of vanadium tetrachloride and sulfur dichloride is performed by the condenser 14. Subsequently, a mixed solution of vanadium tetrachloride and sulfur dichloride was distilled by a pressure distillation method having a top pressure of 5 kg / cm 2 g or more and 15 kg / cm 2 g or less. Is carried out in a distillation apparatus 16 in a step of discharging a vanadium tetrachloride solution from the bottom of the column. |
