摘　　要：The extractive removal of sulfur compounds （S-compounds） from Dongying and Liaohe diesel fuels with [BF4]^--based ionic liquids were systematically investigated. The results show that the absorption capacity of an ionic liquid for the S-compounds in diesel fuels relies on its structure and its size. In the case of the two examined diesel fuels, both elongating the cation tail length and increasing the mass ratio of ionic liquid/diesel fuel promote the desulfurization ability of the examined ionic liquids. The results also show that imidazolium-based ionic liquids display higher extraction efficiencies than pyridinium-based ionic liquids, presumably owing to the fact that the rings of the S-compounds are similar to the imidazolium head ring. With the 1 ： 1 mass ratio of ionic liquid/diesel fuel, the rates of the first desulfurization of Dongying and Liaohe diesel fuels using [C8mim][BF4] amount to 29.96% and 39.76%, suggesting that [C8mim][BF4] is a promising extractant for desulfurization of these diesel fuels.从 Dongying 和 Liaohe 柴油与的硫混合物(S 混合物) 的引得出的移动[BF4 ]? 基于的离子的液体系统地被调查。结果证明为在柴油的 S 混合物的离子的液体的吸收能力依靠它的结构和它的尺寸。在二检验柴油的情况中，两个都伸长阳离子尾巴长度并且增加离子的液体 / 柴油机燃料的集体比率支持检验离子的液体的 desulfurization 能力。结果也证明基于 imidazolium 的离子的液体比基于 pyridinium 的离子的液体显示更高的抽取效率，大概由于 S 混合物的戒指类似于 imidazolium 头的事实响。与 1：离子的液体 / 柴油机燃料的 1 集体比率， Dongying 和 Liaohe 柴油用的第一 desulfurization 的率[C8mim ][BF4 ] 数量到 29.96% 和 39.76% ，建议那[C8mim ][BF4 ] 是为这些柴油的 desulfurization 的有希望的提炼之物。
