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%.
