英文摘要: can be lowered from about 500 ppm to 0.1 ppm without changing the properties of the diesel. The catalyst demonstrates high performance ( greater than or equal to 96% efficiency of H2O2, is easily recycled, andA [(C18H37)(2)N+ (CH3)(2)](3)[PW12O40] catalyst, assembled in an emulsion in diesel, can selectively oxidize the sulfur-containing molecules present in diesel into their corresponding sulfones by using H2O2 as the oxidant under mild conditions. The sultones can be readily separated from the diesel using an extractant, and the sulfur level of the desulfurized diesel similar to100% selectivity to sulfones). Metastable emulsion droplets (water in oil) act like a homogeneous catalyst and are formed when the catalyst (as the surfactant) and H2O2 (30%) are mixed in the diesel. However, the catalyst can be separated from the diesel after demulsification.
