摘要

摘要: 对先锋褐煤在离子液体1-丁基-3-甲基咪唑四氟硼酸盐([Bmim]BF₄)中于温和条件下(350 ℃)的加氢液化行为进行了研究.主要考察了催化剂FeS、ZnCl₂、AlCl₃和FeCl₃对先锋褐煤在离子液体[Bmim]BF₄中液化性能的影响规律,并对液化产物进行了红外光谱分析.研究发现,先锋褐煤在离子液[Bmim]BF₄、催化剂和四氢萘(THN)作用下具有较好的液化性能.在350 ℃、[Bmim]BF₄和ZnCl₂作用下,先锋褐煤的液化产物产率为66.2%,主要的液化产物为四氢呋喃可溶物(THFS)、四氢呋喃不溶而N-甲基吡咯烷酮可溶的产物(NS).液化产物的红外光谱分析结果表明,催化剂的种类显著影响液化产物的分布和结构.

Abstract: The liquefaction behaviors of Xianfeng lignite (XL) in ionic liquid 1-butyl-3-methyl-imidazolium tetrafluoroborate ([Bmim]BF₄) under mild condition-350 ℃ were studied. The effect of catalysts (FeS, ZnCl₂, AlCl₃ and FeCl₃) on the XL liquefaction in [Bmim]BF₄ were investigated and the liquefaction products obtained were analyzed by FT-IR spectra. It is found that the XL has a good hyrogenation activity in the presence of [Bmim]BF₄, catalysts and tetralin (THN). XL liquefied product yield reaches to about 66.2% and the main liquefaction product is heavy fraction-tetrahydrofuran soluble (THFS) and tetrahydrofuran insoluble/N-methyl-2-pyrrolididinone soluble fractions (NS). The analyses of liquefied product by FT-IR show that the type of catalyst significantly affects the distrubution and structure of liquefied product.
