摘要
Three decatungstates with short carbon chains as the cations, such as tetrabutylammonium decatungstate ([(C4H9)(4)N](4)W10O32), tetramethylammonium decatungstate ([(CH3)(4)N](4)W10O32), and benzyltriethylammonium decatungstate ([(C2H5)(3)NC7H7](4)W10O32), Were synthesized and then used as a catalyst in the extractive catalytic oxidative desulfurization (ECODS) system in the ionic liquid (IL) of [Bmim]PF6, and hydrogen dioxide (H2O2) was used Lis an oxidant. During the optimized process, the Sulfur level in the model oil (1000 ppm S) can be reduced to 8 ppm, which is consistent with the Standards of deep desulfurization. The temperature, the reaction time, and the amount of H2O2 and catalyst, as well as the type of the cations of decatungstates, all played vital roles in desulfurization efficiency, which were studied in detail to optimize the reaction conditions. The system could be recycled five times before the sulfur removal decreased sharply.
