神府和胜利煤液化残渣CS_2萃取物的组成分析

Chemical Compositions of Carbon Disulfide Extractable Fraction of Shenfu and Shengli Coal Liquefaction Residue

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.

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, ali- phatic hydrocarbons and heteroatom-containing compounds. Most of arenes are non-substituted arenes and substituted arenas with four to seven rings and benzo[ghi]perylene is the most abundant polycyclie 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.
