Abstract EN
Spent hydrodesulfurization (Co-Mo / γ-Al2O3) catalyst generally contains valuable metals like molybdenum (Mo), cobalt (Co), aluminium (Al) on a supporting material, such as γ-Al2O3.
In the present study, a two stages alkali / acid leaching process was conducted to study leaching of cobalt, molybdenum and aluminium from Co-Mo / γ-Al2O3 catalyst.
The acid leaching of spent catalyst, previously treated by alkali solution to remove molybdenum, yielded a solution rich in cobalt and aluminium.
