Abstract
A process for the hydrodesulfurization of feedstocks under comparatively low hydrogen partial pressures, i.e. less than about 1200 psig (8.27 MPa) in contact with a catalyst containing a hydrogenation component supported on a particular carrier. The carrier is a substantially silica-free alumina prepared by calcining a material comprising a dried alumina (i) containing from about 1.2 to about 2.6 moles of water of hydration per mole of Al.sub.2 O.sub.3, (ii) having an (020) line width at 14.degree. (2 .theta.) at 3/4 maximum intensity of from about 2.0.degree. to about 5.0.degree., and (iii) having an intensity ratio relative to the intensity at 10.degree. (2 .theta.) of about 1.3 to about 5.0.
