In the management of spent catalyst, the refiner must decide if recovery and reuse is a viable option to consider. Oxyregeneration to remove carbon and sulfur deposits and restore activity is commonly practiced for a wide range of hydroprocessing catalysts. A considerable amount of spent material has not been considered for recovery and reuse, however, because it contained high levels of broken or metals contaminated particles, or, because of commingling of two or more different types of catalyst. Until recently, no physical separation techniques were commercially available to the refiner for the recovery of good quality catalyst which has been intermixed with poorer quality material.
