  In this research, desulfurization of diesel from Tehran Refinery was investigated by oxidation method. To investigate this process, the performance of different advanced oxidation systems (acetic acid/hydrogen peroxide, formic acid/hydrogen peroxide) along with acetonitrile extraction were investigated for desulfurization of diesel fuel with 13370 ppm primary sulfur in a discontinuous reactor. The effect of different operating factors such as molar ratio of acid to sulfur (nacid/ns) (15, 20, and 25), molar ratio of hydrogen peroxide (oxidant) to sulfur (no/ns) (5, 10, and 15), temperature and also reaction time were investigated. Many tests showed that in the optimal conditions for removing sulfur from gas oil with the acetic acid/hydrogen peroxide system, the amount of sulfur reached to 9130 ppm with an efficiency of 31%, and with the formic acid/hydrogen peroxide system, the amount of sulfur reached to 2500 ppm with an efficiency of 81%. Also, the examination of the experiments confirmed this point that it is not possible to completely remove the sulfur from heavy oil fractions such as diesel with normal oxidative desulfurization methods.
