Recovery of Valuable Metals from Spent Hydrogenation Catalysts

Abstract:

The recovery method and process of tungsten, nickel and aluminum from spent catalyst was investigated, which had realized the comprehensive recovery of valuable metals about tungsten, nickel and aluminum. The results showed that leaching rate of WO₃ was above 95% and the recovery was 90.85%, nickel and aluminum leaching rate were 98.27% and 90% respectively, the recovery were 91.83% and 92.78% respectively. It had got the conclusion that the technological process was developed, low-cost, high-extraction and process feasibility with good economic benefits and environmental benefits.
