Patent ID: 8883673

Claim:
A composition for use as a distillate hydrodesulfurization catalyst in the manufacture of an ultra-low sulfur distillate product, wherein said composition comprises: a calcined mixture made by calcining a co-mulled mixture comprising an inorganic oxide material, molybdenum trioxide in the form of finely divided particles having a maximum dimension of less than 150 μm, and a Group VIII metal compound selected from the group consisting of a nickel compound, a cobalt compound and a combination thereof, wherein said calcined mixture has a molybdenum content in the range of from 10 weight percent to 22 weight percent with the weight percent being based upon the molybdenum as metal and the total weight of said calcined mixture, and a Group VIII metal content in the range of from 3 weight percent to 12 weight percent with the weight percent being based upon the Group VIII metal in its elemental form and the total weight of said calcined mixture, wherein said calcined mixture further comprises a promoter component selected from the group of phosphorous compounds, wherein said calcined mixture has a mean pore diameter in the range of from 50 angstroms to 100 angstroms, and wherein said calcined mixture has less than or equal to 66.14% of the total pore volume contained in pores of 150 angstroms or less in diameter.
