microwave-assisted oxidative desulfurization (ods) of diesel fuel

The ods process is an important process for the removal of sulfur compounds from fuel oil# in this work, we studied the effect of microwave irradiations on oxidative desulfurization of a diesel oil (diesel oil with initial sulfur content 2640ppmw), using formic acid and hydrogen peroxide as oxidation system# in this study, the influences of various operating parameters such as reaction temperature, molar ratio of oxidant to sulfur and molar ratio of acid to sulfur were investigated# the results showed that by an increase in the reaction temperature and molar ratio of acid to sulfur and oxidant to sulfur, the efficiency of ods process increased# the best sulfur removal from diesel oil in the present oxidative desulfurization system was 89#56%#
