Zusammenfassung:An improved hydroprocessing slurry catalyst is provided for the upgrade of heavy oil feedstock. The catalyst comprises dispersed particles in a hydrocarbon medium with the dispersed particles have an average particle size ranging from 1 to 300 μm. The catalyst has 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. The catalyst is prepared from sulfiding and dispersing a metal precursor solution in a hydrocarbon diluent, the metal precursor comprising at least a Primary metal precursor and optionally a Promoter metal 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.
