综述了从废催化剂中回收铂族金属的各种工艺。由于其广泛的工业应用和较高的市场价格，PGM的回收是有趣的。从可再生资源利用和环境保护的角度来看，随着废催化剂数量的急剧增加，PGMS的回收利用受到了广泛的关注。从废催化剂中回收PGM是一项挑战，因为废催化剂的材料和成分组成以及原始催化剂的制造工艺都是多样化和复杂的。介绍了火法和湿法从废催化剂中回收PGMS的研究现状，分析了这两种技术存在的优缺点。本文还指出，PGM回收工艺具有经济、环保、规模化等优点。(C)2015爱思唯尔B.V.保留所有权利。
This paper provides an overview of the various processes used in the recovery of platinum group metals (PGMs) from spent catalysts. PGM recovery is interesting due to their vast industrial applications and high market prices. From the use of renewable resources and environmental protection viewpoints, recycling of PGMs receives wide concerns as the amounts of spent catalyst increases dramatically. PGM recovery from spent catalysts is a challenge due to the fact that spent catalysts are diverse and complex in terms of material and component makeup as well as the original catalyst's manufacturing processes. The state of the art recovery of PGMs from spent catalysts by pyrometallurgy and hydrometallurgy techniques is highlighted and existing advantages and disadvantages of these techniques are analyzed in this paper. This review also pointed out that the promising processes of PGM recovery are economical, environmentally friendly and large-scale means. (C) 2015 Elsevier B.V. All rights reserved.
