Title: Development of a hydrometallurgical route for the recovery of molybdenum from spent hydrodesulphurization catalyst using Cyphos IL 104

Abstract: This study investigates the partition of molybdenum in presence of hydrochloric acid with Cyphos IL 104 diluted in toluene and recovery of molybdenum from spent hydrodesulphurization catalyst. Effect of various parameters has been estimated. Recyclability and loading capacity have been assessed. Influence of temperature confirmed the process to be endothermic in nature. Binary separations of molybdenum have been achieved with high separation factors. Optimized conditions have been fused for molybdenum recovery from spent hydrodesulphurization catalyst leach liquor. McCabe–Thiele diagrams have been constructed. Molybdenum is finally obtained as MoO3 from the strip solution and characterized by XRD, FE-SEM and EDX techniques. © 2018 The Korean Society of Industrial and Engineering Chemistry
