Self-activated hydrotreating catalyst and method for treating heavy hydrocarbon feedstock

摘要

Processing heavy hydrocarbon raw materials containing fired particles provided by molding and firing a co-kneaded mixture made by co-kneading inorganic oxide powder, molybdenum trioxide powder, and nickel compound To self-activate catalyst. The calcined particles comprise 1 to 10% by weight of molybdenum and an amount of nickel such that the weight ratio of nickel to molybdenum is less than 0.4. The calcined particles have a pore size distribution that contributes to the unique properties of the catalyst. The calcined particles and catalyst also exhibit a unique Raman spectrum. The self-activating catalyst is activated when contacted with a residual oil feedstock having high nickel, vanadium and sulfur concentrations under appropriate process conditions.
