Abstract
The possibility of using of the catalytic system based on formic acid and a transition metal salt in the presence of hydrogen peroxide for desulfurization of nonhydrotreated vacuum gas oil has been explored. Conditions for effective oxidation of organic sulfur compounds and maximal extraction of oxidized compounds from the feedstock have been selected. It has been shown that the catalysts based on tungsten salts are the most effective those for oxidative desulfurization of heavy feedstock. Under optimum conditions, the degree of desulfurization of vacuum gas oil was 89%.
