Desulfurization of Fuel by [Bmim]CoCl3 and Potassium Monopersulfate

Functional ionic liquid [Bmim]C°Cl3 was prepared with potassium monopersulfate compound (PMS) to form extraction catalytic oxidative desulfurization system for benzothiophene (BT) removal. The best reaction conditions for removing BT were as follows: m (ionic liquid) = 2 g, m(PMS) = 1.5 g, C (initia...

Description
Summary:Functional ionic liquid [Bmim]C°Cl3 was prepared with potassium monopersulfate compound (PMS) to form extraction catalytic oxidative desulfurization system for benzothiophene (BT) removal. The best reaction conditions for removing BT were as follows: m (ionic liquid) = 2 g, m(PMS) = 1.5 g, C (initial sulphur) = 500 ppm, T = 40°C ~ 50°C. The desulfurization rate could be reached at 92.4 %. The ionic liquid still had higher activity after 5 cycles of reuse which exhibited that there was only a slight difference in the amount of the oxidant. It was proved that [Bmim]C°Cl3 ionic liquid combined with oxidant PMS has an excellent desulfurization performance.
