Two routes were used to rejuvenate spent residue hydroprocessing catalysts by leaching foulant metals. In the first, deoiled spent catalyst containing coke and deposited metals in sulfide form was chemically treated to remove the metal foulanta. In the second, deoiled spent catalyst was decoked by c
