        A silica–alumina supported Pd–Pt bimetallic catalyst was found to   be highly active in dibenzothiophene hydrodesulfurization with   preferential selectivity to the hydrogenation (HYD) route of   desulfurization at the expense of the direct removal of sulfur.   In addition, it was demonstrated that for Pd–Pt catalysts   selectivity to HYD can be drastically changed by a “soft” change   in the nature of the carrier.
