| 中文摘要: |
| 失效重整催化剂是贵金属回收企业重要的原料。对比了硫酸溶解载体法、盐酸溶解法、混酸溶解法、碱溶载体法以及火法工艺处理失效重整催化剂的基本流程，研究了铂回收和氧化铝综合利用的路线，分析了各种方法的优势和不足。结合我国环保政策要求，提出了加压碱溶解载体法是目前最佳的工艺选择，需要进一步深入开展研究。 |
| 英文摘要: |
| Spent reforming catalysts are important raw materials for precious metal recovery plants. The basic processes of dissolving the carriers in spent reforming catalysts by sulfuric acid , hydrochloric acid, mixed acid and alkali and the pyrometallurgy method were compared. The routes of platinum recovery and aluminum comprehensive utilizationwere studied, and their advantages and disadvantageswere analyzed. Combined with the requirements of China's environmental protection policies, it was proposed that the pressurized alkali dissolution carrier method was the best option at present. |
