摘要
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° (2 &thgr;) at 3/4 maximum intensity of from about 2.0° to about 5.0°, and (iii) having an intensity ratio relative to the intensity at 10° (2 &thgr;) of about 1.3 to about 5.0.
