Process for Recovering Base Metals from Spent Hydroprocessing Catalyst |
| abstract |
A method for recovering metals from a spent dispersed catalyst originating from a Group VIB metal sulfide catalyst containing at least a Group VB and Group VIII metal for hydrocarbon oil hydroprocessing is disclosed. In one embodiment, the method comprises the steps of: contacting the spent dispersed catalyst with a leaching solution containing ammonia and air to dissolve the group VIB metal and the Group VIII metal into the leaching solution at sufficient temperature and pressure; forming a slurry containing at least a group VIB metal complex and at least a group VIII metal complex, ammonium sulfate and solid residue containing at least a Group VB metal complex and coke; separating and removing the solid residue containing ammonium metavanadate and coke from the pressure leach solution (PLS); precipitating from the PLS at least a portion of the Group VIB metal and at least a portion of the Group VIII metal by controlling the pH at a pre-selected pH to selectively precipitate as metal complexes the Group VIB and Group VIII metals. |
