Catalytic oxidative desulfurization of gasoline over D072 resin at room temperature and atmospheric pressure

In order to meet more and more strict policy of environment protection, an investigation into the oxidative desulfurization (ODS) process for gasoline was carried out to use an oxidant (H₂O₂) over the D072 resin catalyst . The reaction conditions including the temperature, the amounts of oxidant and the reaction time were studied and discussed. The experimental results show that a maximum sulfur compounds removal of 75% is obtained in the presence of H₂O₂ with an O/S molar ratio of 17 at room temperature (RT) and atmospheric pressure, which can make a simple and cheap process. The possible mechanism was also disscussed in the study.
