Described is a catalyst useful in the hydroprocessing of a heavy hydrocarbon feedstock wherein the catalyst comprises a calcined mixture made by calcining a formed particle of a mixture comprising molybdenum trioxide, a nickel compound, and an inorganic oxide material. The catalyst may be made by mixing an inorganic oxide material, molybdenum trioxide, and a nickel compound to form a mixture that is formed into a particle and calcined to provide a calcined mixture. The process involves the hydrodesulfurization and hydroconversion of a heavy hydrocarbon feedstock which process may include the conversion of a portion of the pitch content of the heavy hydrocarbon feedstock and the yielding of a treated product having an enhanced stability as reflected by its P-value.
