:Aluminum recovery is a key issue for the overall recycling of valuable metals from spent catalysts. This paper focuses on the recovery and regeneration of alumina with high additional value from the spent hydrodesulfurization catalyst CoMo/Al2O3. The results indicate that 98.13% alumina is successfully leached from the treated spent catalysts......
