Patent ID: 8080492

Claim:
A catalyst precursor, upon sulfidation, forms a bulk multi-metallic catalyst for hydrotreating a hydrocarbon feed under hydroprocessing conditions, the catalyst precursor comprising at least a Group VIB metal compound; at least a promoter metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof; optionally at least a ligating agent; optionally at least a diluent; wherein the catalyst precursor has an essentially monomodal pore size distribution with at least 90% of the pores being macropores and a total pore volume of at least 0.08 g/cc; wherein the catalyst precursor is a hydroxide; and wherein the catalyst precursor is made in a process wherein the steps before sulfidation to form the bulk multi-metallic catalyst are carried out at a temperature of 200° C. or less and wherein the catalyst precursor remains a hydroxide before sulfidation to form the bulk multi-metallic precursor.
