燃料油燃烧和石油炼制过程中会产生石油基飞灰,有较高的环境风险,但同时其富集的钒、镍、钼又是有价金属元素,具有资源化潜力。综述了从石油基飞灰中回收有价金属的研究进展,对其中的焙烧、浸出工艺进行了重点讨论。

Petroleum-based fly ash will be generated in the process of fuel oil combustion and petroleum refining,which may bring high environmental risks.It contains high contents of vanadium,nickel and other high value metals,which have the potential to be recycled.The research progress on recovering valuable metals from:petroleum-based fly ash is reviewed,with emphasis on the leaching and solvent extraction processes.
