The invention relates to a bulk multi-metallic catalyst for hydrotreating heavy oil feeds and to a method for preparing the catalyst. The bulk multi-metallic catalyst is prepared by sulfiding a catalyst precursor having a poorly crystalline structure with disordered stacking layers, with a type IV adsorption-desorption isotherms of nitrogen with a hysteresis starting point value of about 0.35, for a sulfided catalyst that will facilitate the reactant's and product's diffusion in catalytic applications. In another embodiment, the precursor is characterize...
1. A catalyst precursor, upon sulfidation, forms a bulk multi-metallic catalyst for hydrotreating a hydrocarbon feed under hydroprocessing conditions, the catalyst precursor is formed by reacting to form a precipitate: at least two Group VIB metal compounds; at least a promoter metal compound; at least a ligating agent L; optionally at least a diluent, the promoter metal compound is nickel and the at least two Group VIB metal compounds are molybdenum and tungsten;wherein the precipitate is formed without addition of any sulfur compounds to the reaction;w...
