    摘要: Sulfur-containing petroleum distillates are desulfurized with hydrogen and with a catalyst composite containing a Group VI-B hydrogenating component, at least one iron group hydrogenating component and alumina. The catalyst is prepared by calcining alumina having a bayerite content of 0-50 wt. percent, at a temperature of 800*-1600*F, impregnating the calcined alumina with the hydrogenating components and calcining the impregnated alumina at 800*-1600*F. The composite catalyst is characterized as having a pore volume of at least 0.5cc/g, a surface area of at least 150 m2/g and an average pore radius of 45 to 75 Angstrom units. At least 65 percent of the pore volume of the composite catalyst is in pores having a radius in the range of 50 - 300 Angstrom units.

    摘要: A multiple stage process is described for the catalytic hydrodesulfurization and hydrodemetallization of a residual petroleum oil boiling above the gasoline range. The product of the process comprises essentially material boiling above the gasoline range and comprises little material boiling below the initial boiling point of the residual oil feed. The hydrodesulfurization-demetallization process comprises an initial stage involving relatively high hydrogen pressure in the presence of a catalyst comprising a relatively low proportion of catalytically active hydrogenation metals. The process employs a final stage in series having a relatively lower hydrogen pressure and a catalyst comprising a relatively higher proportion of hydrogenation metals. The stream entering the final stage contains an amount up to 10, 20 or even 25 weight percent of the asphaltene content of the charge to the first stage while the effluent from the final stage is essentially free of asphaltenes.
