先锋褐煤在离子液体中温和加氢转化研究
, PP. 922-927
Keywords: 液化,褐煤,离子液体
Abstract:
？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.
