Catalysts containing 2.8-20.6Vertical Bar3< molybdenum on silica or 3.7-27.6Vertical Bar3< of a mixed cobalt-molybdenum oxide containing 36Vertical Bar3< cobalt were studied by hydrogen reduction, pore size distribution, X-ray analysis, diffuse reflectance spectroscopy, and analytical electron microscopy. The results suggested that the differences between the molybdenum and cobalt-molybdenum hydrodesulfurization catalysts are only quantitative and that their activity differences depend mainly on their dispersion in the sulfided form, which in turn depends on the dispersion of the oxide precursors.
