| 摘 要： | 采用气相色谱/质谱联用研究分析了胜利褐煤在0.1t/d直接液化连续实验装置上所得煤液化油中酚类化合物的分布特征.实验通过碱液洗涤法富集煤液化油中混合酚组分,并对该组分进行衍生化处理,以提高色谱柱对混合物的分离性能.以混合衍生物为主要分析对象,共定性出煤液化油中134种个体酚,分属于苯酚、茚满酚、萘满酚和萘酚等四种类型,且绝大多数酚类化合物都带有烷基侧链.苯酚类化合物数量最多,在混合酚组分中含量最大,其次为茚满酚和萘满酚.萘酚类化合物的数量最少,相对含量最小. |

| Abstract: | The distribution and characterization of phenolics in direct coal liquefaction (DCL) oil have been quantified by gas chromatography/mass spectrometry (GC/MS).The oil was from 0.1 t/d BSU liquefaction run feeding with Shengli brown coal.The phenolic concentrate in DCL oil was isolated through caustic extraction,and then was further derivatizied to prepare derivative mixture,which was the main sample for GC/MS analysis because of its higher separability compared to the concentrate.Totally,134 phenolics,which ... |
