Sonocatalytic oxidative desulfurization of oil from the Zhanazhol oilfield

Abstract

Sonocatalytic oxidative desulfurization of oil from the Zhanazhol oilfield was investigated. Application of stepwise periodic treatment in an ultrasound field in the presence of a Ni-skeletal catalyst and oxidizer was shown to be an effective procedure for improving the quality of oil and oil-based products, which allowed targeted change of its chemical composition, increasing the yield of light products (gasoline and diesel fractions from 15.6 to 21.9 and from 47.7 to 58.6 wt %, respectively) and decreasing the sulfur content in oil products to 49%.
