Peroxide-Assisted Oxidative Desulfurization of Nonhydrotreated Vacuum Gas Oil

Resumo

The possibility of using a catalyst system based on hydrogen peroxide and formic acid for the oxidative desulfurization of nonhydrotreated vacuum gas oil has been explored. Conditions for the effective extraction of oxidized sulfur compounds from nonhydrotreated vacuum gas oil have been selected. The effect of oxidation and thermolysis conditions on the oxidative desulfurization process has been studied, and a 44% decrease in the total sulfur content in nonhydrotreated vacuum gas oil has been achieved.
