ABSTRACT:
A catalyst for the hydrotreatment of heavy crudes and their residues, and a method of preparing same, is disclosed, which has significant simultaneous hydrodemetallizing and hydrodesulfurizing activity. The catalyst is prepared by successively impregnating an extruded refractory support with a Group VIb and a Group VIII metal, calcining the pellet thus produced, and presulfurizing same. Pore volume of the catalyst ranges between 0.50 and 1.2 ml/g, total surface area ranges between 120 and 140 m.sup.2 /g, at least 60% of said pore volume consists of pores having diameters greater than 100 .ANG., and x-ray photoelectron spectroscopy signal band strength ratios are as follows: I(Me VIb)/I(refractory metal) is between 5 and 8, and I(Me VIII)/I(refractory metal) is between 1 and 5. The novel catalyst has a useful life greater than conventional catalysts for the simultaneous hydrodemetallization and hydrodesulfurization of continuous feeds of heavy hydrocarbons, as shown by the fact that it exhibits no substantial reduction in catalytic activity over an 80 day period.
