Patent ID: 7964524

Claim:
A method for using rework material generated in the process of forming a bulk multi-metallic catalyst, the method comprising: forming a precipitate comprising at least a promoter metal precursor, at least a Group VIB metal precursor, optionally at least a ligating agent, and optionally at least a diluent, wherein the promoter metal precursor is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, wherein the precipitate is a hydroxide; removing at least 50% of liquid from the precipitate by any of decanting, filtering, settling, and drying; adding the rework material to the precipitate forming a batch mixture, wherein the rework is a hydroxide; shaping the batch mixture into a shaped catalyst precursor via any of pelletizing, extrusion, tableting, molding, tumbling, pressing, spraying and spray drying; and sulfiding the shaped catalyst precursor forming the bulk multi-metallic catalyst; wherein the steps before sulfiding are carried out at a temperature of 200° C. or less and wherein the catalyst precursor remains a hydroxide before sulfiding.
