摘要
Abstract
Spent hydroprocessing catalyst,a hazardous waste generated in petroleum refining industry, can be used as raw materials for metal recovery in order to meet the circular economic requirements of reducing,reusing and recycling. In light of that,this paper reviews the metal recovery and reuse of spent hydroprocessing catalyst. The methods are divided into hydrometallurgical route and pyrometallurgical route after pretreatment. The hydrometallurgical route contains direct leaching and roasting with alkali compounds. The roasting of spent catalysts with sodium and/or potassium salts significantly enhances solubility of some metals in water,which makes the subsequent leaching process easier. The downsides of this approach are equipment corrosion and secondary pollution. This paper also introduces some commercial metal recovery routes,including acid leaching,alkali leaching,water leaching with roasting and pyrometallurgy. Furthermore,the future research directions are shortening the route in the hydrometallurgical process and lowering energy consumption in the pyrometallurgical route.关键词
