| 失效汽车尾气催化剂是铂族金属重要的二次资源。介绍了汽车尾气净化催化剂的发展历程和资源状况，重点综述了从失效汽车尾气催化剂中回收铂族金属的富集技术。这些技术包括火法技术的金属捕集法及氯化气相挥发法，湿法技术的活性组分溶解法、载体溶解法、全溶法及加压高温氰化法等，对这些技术的优势和不足进行了分析。提出优化工艺、资源综合利用的发展方向。 |
| 英文摘要: |
| The spent automotive exhaust catalysts are an important secondary resource of platinum group metals. The development history and resource status of automobile exhaust gas purification catalyst were introduced, and some enrichment techniques of recovering platinum group metals from spent automotive exhaust catalysts were reviewed. These technologies include metal capture and chlorination gas phase volatilization method of fire methods, and active component dissolution method, carrier dissolution method, total dissolution method and pressurized high temperature cyanidation method of wet methods. The advantages and disadvantages of these technologies were analyzed. The development direction of optimization process and comprehensive utilization of resources was proposed. |
