Abstract

A method for preparing an improved slurry catalyst for the upgrade of heavy oil feedstock is provided. In one embodiment, the process comprises: sulfiding at least a metal precursor solution with at least a sulfiding agent forming a sulfided Group VIB catalyst precursor, the metal precursor solution having a pH of at least 4 and a concentration of less than 10 wt. % of Primary metal in solution; and mixing the catalyst precursor with a hydrocarbon diluent to form the slurry catalyst composition. The slurry catalyst prepared therefrom has a BET total surface area of at least 100 m/g, a total pore volume of at least 0.5 cc/g and a polymodal pore distribution with at least 80% of pore sizes in the range of 5 to 2,000 Angstroms in diameter.
