Aerobic Oxidation of Organosulfur Compounds in the Presence of Fe3O4 Nanoparticles
摘要
Abstract—Aerobic oxidation of organosulfur compounds of petroleum origin by atmospheric oxygen was performed using a heterogeneous catalyst in the form of Fe3O4 nanoparticles. By studying the oxidation of model mixtures (a solution of dibenzothiophene in decalin), the following conditions for the complete oxidation of dibenzothiophene were selected: catalyst weight, 1 mg; temperature 130°C; and time, 180 min. The catalyst remains active throughout five oxidation cycles. Physicochemical studies showed that the phase composition and structure of the catalyst persist after the regeneration stage.
