The aim is to explore the recovery of critical metals, specifically Mo, Ni, and V, from spent hydrotreating catalysts using deep eutectic solvents.
Utilized a series of deep eutectic solvents for extraction.
Analyzed the efficiency of metal recovery processes.
Conducted comparative studies with traditional recovery methods.
Successfully recovered significant amounts of Mo, Ni, and V.
Demonstrated higher efficiency compared to conventional methods.
Highlighted the environmental benefits of using deep eutectic solvents.
Abstract
Spent residue hydrotreating catalysts represent a valuable secondary source of critical metals such as molybdenum (Mo), nickel (Ni), and vanadium (V). In this study, a series of deep eutectic solvents...
