摘　　要：总结了从失效催化剂中回收钌的多种方法和工艺,重点介绍了常用的熔融氧化蒸馏法。熔融氧化蒸馏法由于工艺繁杂、步骤冗长、对设备要求高等缺点,近年来不同学者和行业专家先后提出了还原沉淀法、直接氧化法和活泼金属置换法等方法,但尚未有工业化应用的报道。简化工艺流程、提高钌的回收率是目前钌回收研究工作并实现其工业化生产的重点和难点。The various methods and processes for recovering ruthenium from spent catalysts are reviewed.Melting oxidative distillation is currently the most mature and widely used method in industry.Due to the complicated process,long steps,high requirements for equipment in industrialization,in recent years,scholars and industry experts have proposed process technologies such as reduction precipitation,direct oxidation,and displacement,but there have been no reports of industrial applications.Thus simplifying the process and improving the recovery rate of germanium,it is the focus and difficulty of the current research work on recycling.
