الملخص الانجليزي
In the present research, hydro – desulfurization spent catalyst with an alumina base has been found to be as a source for molybdenum recovery. It was compose of 19 - 30 % of molybdenum as MoO3. Two methods were used for the recovery of molybdenum. First method was using H2S gas for precipitation of Co as CoS, and the precipitation of Mo has been done by HCl acid solution addition. The second method was the alkali leaching of spent catalyst and recovery of molybdenum using dilute NH4OH solution and then the precipitation of molybdenum as trioxide using HCl solution. The optimum conditions were predicated for the recovery of molybdenum, and different parameters were studied such as the alkali concentration and leaching time.
