摘要：A process for selective hydrodesulfurization of a sulfur and olef in-containinghydrocarbon feedstock boiling in the naphtha or gasoline boiling range utilizing aparticularly defined high activity hydrodesulfurization (HDS) catalyst compositioncomprising a cobalt component, a molybdenum component and little or no phosphorus,prepared on a special alumina support containing a low concentration of silica and havinga high surface area of at least 280 m2/g. In another aspect the process involvesseparating the feedstock into a light and a heavy fraction, followed by selectivelyhydrodesulfurizing the heavy fraction using a particularly defined high activity HDScatalyst and hydrodesulfurizing the light fraction with a particularly defined highselectivity HDS catalyst. The process also includes performing the separation intofractions and the selective hydrodesulfurization of the fractions in a distillation columnreactor utilizing different particularly defined HDS catalysts.
