| 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. |
