| titleOfInvention | Comprehensive recycling method of platinum-rhenium containing reformed spent catalyst |
| abstract | The invention relates to a comprehensive recycling method of a platinum-rhenium containing reformed spent catalyst. The comprehensive recycling method is used for leaching rhenium by pressurizing and alkaline-dissolving, is used for enriching platinum by normal-pressure acid dissolving, and is also used for comprehensively recycling aluminum oxide. The main flow comprises: (1), grinding material, namely, grinding the platinum-rhenium containing reformed spent catalyst to obtain powder materials with a grain size of 30-100 meshes; (2), pressurizing and alkaline-dissolving, namely, leaching rhenium by adopting a pressurizing method under an alkaline system to obtain leaching liquor L1 and leaching residue S1; (3), refining and rhenium extracting, namely, adding soluble sylvite to the leaching liquor L1 for refining the rhenium; (4), carrying out acid dissolving, namely, dissolving the leaching residue S1 by using an acid solvent to obtain leaching liquor L2 and leaching residue S2; (5), carrying out platinum refining, namely, refining the platinum in the leaching residue S2 to obtain metal platinum; and (6), carrying out aluminum sulfate recycling, namely, crystallizing the aluminum sulfate in the leaching liquor L2 to obtain a water purifying agent. The comprehensive recycling method of the platinum-rhenium containing reformed waste catalyst is simple in process flow and high in platinum and rhenium comprehensive recovery rate, wherein the platinum comprehensive recovery rate is higher than 99%, and the rhenium comprehensive recovery rate is higher than 92%. Meanwhile, the carrier is comprehensively recycled and utilized, so that the comprehensive recycling method is relatively environment-friendly. |
