| titleOfInvention | Method for leaching metal contained in waste catalyst by acid |
| abstract | The invention relates to a method for leaching a metal contained in a waste catalyst by acid, which is used for treating a waste catalyst produced by a hydrodesulfurization process, comprising: a leaching step, immersing the waste catalyst mixture in a high In the oxidizing acid solution, the sulfur in the mixture is reacted with the acid liquid to produce a mixed liquid containing the heavy oil, the decanting liquid and the residue body, and the decanting liquid and the residue are rich in oxidation. a metal removal process; after removing the residue from the mixture, the effluent is separated from the heavy oil by leaching to remove the heavy oil by oil separation, and the decanted liquid is obtained. And a refining step of leaching the metal in the residue to obtain a residue leaching solution for extracting and sinking the metal contained in the eluate and the residue leaching solution, respectively. |
