| Abstract Scope |
With the technological advancement and industrial upgrading of the petrochemical industry, the use of platinum(Pt) and palladium(Pd) in catalysts is also constantly increasing, which leading to a continuous increase in spent petrochemical catalysts containing Pt and Pd. The spent petrochemical catalysts contains about 2000 g/t of platinum group metals(PGMs) and has extremely high recovery value. Therefore, the development of technology for recovering PGMs from spent petrochemical catalysts has the effect of alleviating supply-demand contradiction. This article reviews the recovery methods of PGMs from spent petrochemical catalysts, analyzes the current recovery status and focuses on the application of pressurized alkaline solution in the recovery process of Pt and Pd from spent petrochemical catalysts. The pressurized alkaline solution technology can avoid the problem of high cost in acid solution process wastewater treatment, and is conducive to the recycling of alumina resources, achieving the comprehensive utilization of various components of spent petrochemical catalysts. |
