Abstract:
Due to increasing environmental concern, special interest has been paid to reduction of organosulfur compounds in transportaion fuels. The sulfur- containing compounds are converted into sulfur oxide, i.e, SOx , during combustion, which is a major source of acid rain and air pollution.Gas condensate is a mixture consisting primarily of pentanes and heavier hydrocarbons which is recovered as a liquid from natural gas. It is a proper hydrocarbon source for producing gasoline, kerosene and gas oil in refineries. In this reseach a gas condensate was used as feedstock for studing oxidative desulfurization (ODS). The influence of various parameters of desulforization including the reaction temperature, hydrogen peroxide to sulfur molar ratio ( O/S), acetic acid to sulfur molar ratio ( C/S), reaction time and number of oxidation steps were investigated in details. The appropriate oxidation conditions were found to be the reaction temperature=65℃, O/S molar ratio=10, C/S molar ratio=40, time=60min. The efficieny of the ODS process under these appropriate reaction was found to be 91%
