摘　　要：采用气相色谱-氢火焰离子化检测器法(GC-FID)确定了色谱条件;采用全二维气相色谱-飞行时间质谱/氢火焰离子化检测器法(GC×GC-TOF MS/FID)分析,得到煤直接液化石脑油中单体化合物的组成信息,将化合物按z值分类法进行分类,共得到5种族类别化合物,极性由低到高依次为链烷烃类、一环烷烃类、二环烷烃类、烷基苯类和一环烷苯类化合物,其中芳烃类化合物共检测到13种,12种为烷基苯类,1种为茚满;采用气相色谱-飞行时间质谱/氢火焰离子化检测器法(GCTOF MS/FID)分析,定性定量128种单体化合物,其中大部分为环烷烃类,少量为链烷烃类,环烷烃类化合物多为带侧链的环戊烷和环己烷的同分异构体。The chromatographic conditions were determined by gas chromatography-hydrogen flame ionization detector(GC-FID).The composition informations of monomer compounds in direct coal direct liquefaction naphtha were determined by comprehensive two-dimensional gas chromatography combined with time-of-flight mass spectrometry/hydrogen flame ionization detector(GC×GC-TOF MS/FID)analysis.The compounds were classified according to the z-value classification method,and a total of 5 racial compounds were obtained.The order of polarity from low to high were alkanes,monocycloalkanes,bicyclic alkanes,alkylbenzenes,and monocyclobenzenes.13 aromatic compounds were detected in total,12 compounds were alkylbenzenes,and 1 compound was indene.128 monomer compounds were qualitatively and quantitatively identified by gas chromatography-time-of-flight mass spectrometry/hydrogen flame ionization detector(GC-TOF MS/FID).Most of them were cycloalkanes,and some of them were alkanes.Cycloalkane compounds were mostly isomers of cyclopentane and cyclohexane with side chains.
