Peroxide Oxidative Desulfurization of Crude Petroleum in the presence of fatty acids

Abstract

Oxidative desulfurization of crude petroleum with hydrogen peroxide in the presence of fatty acids has been studied. A procedure for the recovery of oxidized sulfur-containing compounds from the petroleum by extracting the oxidation products with acetone has been selected. The influence of fatty acid on the residual sulfur content and oil viscosity was determined. As a result of oxidative desulfurization, up to 45% of total sulfur is recovered from petroleum, with the viscosity decreasing of crude oil.
