Abstract
A process for preparing a bulk multi-metallic catalyst for hydrotreating heavy oil feeds is provided. The catalyst 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. The bulk multi-metallic catalyst is prepared by sulfiding a catalyst precursor that has an essentially monomodal pore volume distribution with at least 95% of the pores being macropores, and having a total pore volume of at least 0.08 g/cc.
