Recovery method of rhenium from used catalyst |
| abstract |
(57) [Summary] [Structure] A method for recovering rhenium from a catalyst containing rhenium oxide supported on a porous carrier containing alumina. First, the catalyst is heated in an oxidizing atmosphere, then treated with an aqueous hydrogen peroxide solution, and finally rhenium is extracted with a basic aqueous solution (aqueous ammonia solution having a pH of 12 or more). [Effect] According to the method of the present invention, rhenium can be extracted in a high yield, and this extraction solution can be directly used for the production of a new catalyst. |
