| 中文摘要: |
| 失效铂铼催化剂中铂铼性质相似，难以分离，采用碳酸钠加压浸出选择性分离铼，研究了浸出条件对铼浸出效率的影响。在反应温度为160℃，反应时间为150 min，浸出剂碳酸钠用量为物料量的8%，搅拌速率为500 r/min，液固比为4:1，反应压力为0.5 MPa的条件下，铼浸出率98.5%，铂基本不溶解而留在渣中，实现铂和铼的初步分离。 |
| 英文摘要: |
| The properties of platinum and rhenium in spent platinum-rhenium catalysts are similar and they are difficult to separate. Sodium carbonate pressure leaching was used to selectively separate rhenium from spent catalysts. The influence of leaching conditions on the leaching efficiency of rhenium was studied. When the leaching conditions were as follows: 160℃ of reaction temperature, 150 mins of reaction time, 8% leaching agent amount of the material, 500 r/min of stirring speed, 4:1 of liquid-solid ratio, and 0.5 MPa of reaction pressure, the leaching rate of rhenium was 98.5%, and the platinum was almost insoluble and remained in the slag, thus realizing the separation of platinum and rhenium. |
