Oxidative Desulfurization of kerosene refinery in Tehran with sulfur content of 0/293% with iron chloride - hydrogen peroxide and ultrasonic liquid catalysts in the presence of acetic acid - formic acid and an oxidizinghydrogen peroxide has been studied. The effects of operating parameters such as temperature, reaction time, mole ratio of moles of sulfur oxidation (no/ ns),mole ratio of moles of acid per mol of sulfur (n_acid/ n_s (on the desulfurization of kerosene checked(the molar ratio of oxidant to 15-40 and 20-80 mole ratio of sulfur to sulfur acid)The results showed that the optimal conditions for the removal of sulfur from iron chloride catalyst system kerosene by 93% and sulfur content of residual 128 ppm  is obtained. The effect of ultrasonic waves on system performance oxidationwas studied, the results showed that the percentage of desulfurization systems, oxidation of acetic acid- hydrogen peroxide in combination with ultrasound (96%) and without ultrasound was 93%, which indicates improved performance oxidation The presence of ultrasound.
