| 摘 要： | 以CS2作为溶剂,对神府和胜利煤液化残渣进行了常温萃取,利用GC/MS对萃取物进行分析,考察产物中各族组分的分布规律,进而比较两种煤液化残渣的分子结构特征.结果表明:在神府和胜利煤液化残渣的萃取物中分别检测到33和22种化合物,主要由大分子的芳烃、脂肪烃和含杂原子有机化合物组成.芳烃包括4-7环的稠环芳烃及其烷基取代衍生物,其中6环的苯并[ghi]苝含量最高,脂肪烃主要为正构烷烃和取代烷烃,含杂原子有机化合物主要以含氧和含硫元素的化合物为主.

| Abstract: | Shenfu and Shengli coal liquefaction residue were extracted with carbon disulfide and the extracts were analyzed with gas chromatography/mass spectrometry(GC/MS).The results show that 33 and 22 organic compounds were detected in the extracts from Shenfu and Shengli coal liquefaction residue respectively.The extracts mainly consist of arenes,aliphatic hydrocarbons and heteroatom-containing compounds.Most of arenes are non-substituted arenes and substituted arenas with four to seven rings and benzoperylene is the most abundant polycyclic arenes in the GC/MS-detectable species.Aliphatic hydrocarbons primarily consist of n-alkanes and substituted alkanes.Heteroatom-containing compounds mainly consist of oxygen-containing compounds and sulfur-containing compounds. |
