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。The liquefaction behaviors of Xianfeng lignite （XL） in ionic liquid 1-butyl-3-methyl-imidazolium tetrafluoroborate （[Bmim]BF4） under mild condition-350 ~C were studied. The effect of catalysts （FeS, ZnC12, A1C13 and FeC13 ） on the XL liquefaction in [ Bmim ] BF4 were investigated and the liquefaction products obtained were analyzed by PT-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.
