In Situ Generated Organic Peroxides in Oxidative Desulfurization of Naphtha Reformate

The paper describes a method developed for the oxidation of organosulfur compounds using organic peroxides generated in situ under the action of atmospheric oxygen on gasoline fraction after reforming. Naphtha reformate that contained dibenzothiophene as a model substrate was subjected to oxidative desulfurization by organic peroxides generated in situ under atmospheric oxygen. The study examined various catalytic systems, including immobilized Anderson-type polyoxometalates, and initiators, which, in combination, provided effective generation of alkyl hydroperoxides, selective oxidation of organosulfur compounds in the hydrocarbon feedstock, and a high conversion rate.
