摘要
采用溶剂萃取 -化学处理 -柱层析相结合的预处理分离程序、色 -质联用和色 -红联用结合色谱保留值的定性方法 ,分析研究了内蒙东胜煤快速加氢热解焦油的化学成分和结构 ,推测鉴定出2 0 0多种化合物 ,并对具有代表性的 1 9种多环芳烃进行了定量分析 ,讨论了快速加氢热解焦油化学成分的结构特征。
The coal tar sample from Dongsheng coal flash hydropyrolysis (FHP) was grouptype fractionated using solvent extraction, chemical treatment and liquid chromatography on a silica gel column to provide 4 fractions. Subsequently, high resolution separation of individual components was achieved by using capillary chromatography. Over 200 compounds, including aliphatic、hydrocarbon、aromatic and polycyclic aromatic hydrocarbons, azaarenes, phenols, amines, etc., were tentatively identified by GC/MS and checked with GC/FTIR and gas chromatography retention value, and 19 PAHs(containing NPAH and OPAH) were quantitated by capillary GC.The characteristics of the FHP coal tar were discussed.
