摘要
采用梯度洗脱技术对煤液化油进行了分离,并对芳烃部分进行了气相色谱-质谱（GC-MS）和核磁共振氢谱（^1H-NMR）分析。结果表明,通过梯度洗脱技术能够将煤液化油分成轻、中和重芳烃。单环芳烃低场部分质子的特征吸收区域在化学位移（δ）为6.9-7.2处,双环和多环芳烃低场部分质子特征吸收区域在δ为7.2-9.0处。
The coal liquefaction oil was separated using gradient elution method and the aromatics were analyzed by gas chromatography and mass spectrometry （GC-MS） and ^1H-nuclear magnetic resonance （^1H_NMR）. The results show that the aromatics are separated into light-, middle- and heavy-aromatics by the method. The chemical shifts of the proton of aromatics in the low field NMR are at 6.9--7.2 for mono- aromatics as well as 7.2-9.0 for multi-aromatics.
