A highly active hydroprocessing catalyst that comprises an inorganic oxide support particle having been impregnated with a metals-impregnation solution comprising a complexing agent and a hydrogenation metal that is further incorporated with an organic additive blend.

A highly active hydroprocessing catalyst that comprises a doped support impregnated with at lease one hydrogenation metal component and filled with an organic additive blend. The catalyst is made by providing a doped support particle followed by impregnating the doped support particle with a metal impregnation solution to provide a metal-impregnated doped support particle. The metal-impregnated doped support particle is dried but not calcined and impregnated with an organic additive blend component.

An ultra-stable catalyst composition for hydroprocessing hydrocarbon feedstocks and a method of making and use of the ultra-stable catalyst composition. The catalyst composition of the invention comprises a calcined mixture made by calcining a formed particle of a mixture comprising an inorganic oxide material, molybdenum trioxide, and a nickel compound; wherein the calcined mixture is further overlaid with a cobalt component and a molybdenum component to thereby provide the catalyst composition.

The present invention relates to a catalyst precursor for forming a molybdenum disulfide catalyst through a reaction with sulfur in heavy oil and to a method for hydrocracking heavy oil by using same. According to the present invention, the yield of a low-boiling liquid product with a high economic value in the products by heavy oil cracking can be increased, and the yield of a relatively uneconomical gas product or coke (toluene insoluble component), which is a byproduct, can be significantly lowered.
