Oxidative desulfurization of straight-run naphtha fraction in the presence of a heterogeneous catalyst containing two active sites was studied. Combination of an acid component and a transition metal ensures high performance of the oxidative desulfurization catalyst HPMo–NA–SBA-15, in which the SBA-15 support is mesoporous ordered silica. The nicotinic acid fragments bound to the SBA-15 support and phosphomolybdic acid anion by covalent and ionic bonds, respectively, prevent the washout of the phosphomolybdate active phase, thus preserving the catalyst performance in at least five oxidation/regeneration cycles. Conditions were found for obtaining a naphtha fraction with ultralow sulfur content (5 ppm).
