Abstract
A catalyst precursor for preparing a bulk multi-metallic catalyst upon sulfidation is provided. The precursor has an essentially monomodal pore volume distribution with at least 90% of the pores being macropores, and a total pore volume of at least 0.08 g/cc. The bulk multi-metallic prepared from the precursor is particularly suitable for hydrotreating heavy oil feeds having a boiling point in the range of 343° C. (650° F.)—to 454° C. (850° F.), an average molecular weight Mn ranging from 300 to 400, and an average molecular diameter ranging from 0.9 nm to 1.7 nm.
