摘　　要：废氧化铝载体铂催化剂具有极高的价值,从废催化剂中回收铂意义重大。综述了从废氧化铝载体铂催化剂中回收铂的技术现状,并对主要回收工艺存在的优缺点进行了评述。湿法工艺存在难以处理复杂物料和综合利用废液等问题,火法工艺存在对设备要求高和造渣方法局限等问题,尚未大规模工业应用。未来废催化剂数量庞大且成分愈发复杂,开发更加高效清洁的回收工艺是未来的主要发展趋势。With regard to the high content of platinum in alumina supported spent catalyst,it is essential to recover platinum from alumina supported spent catalyst.In this paper,the technical status of platinum recovery from waste alumina supported platinum catalyst is reviewed,and the advantages and disadvantages of the main recovery processes are discussed.Hydrometallurgical process is difficult to deal with complex materials and comprehensive utilization of waste liquid.Pyrometallurgical process is limited by equipment and slag-making methods,so it has not been applied in large-scale industry.Considering the large quantity and complex composition of waste catalysts in the future,it is considered that the development of more efficient and clean recovery process is the main development trend in the future.
