| 摘 要： | 采用经典柱色谱法对煤液化循环油和“加氢”后的循环油进行族组成分离,将其分离成饱和烃、芳香烃和极性物3个组分,并用核磁共振波谱仪对各个组分进行定性分析,同时用气质联用分析方法初步确定了饱和烃和芳香烃两个馏分的主要物质组成。结果表明:循环油饱和烃部分主要由C12~C27直链烷烃组成,芳香烃部分主要组成是烷基取代的氢化单环芳烃及少量的多环芳烃。而循环油经420℃“加氢”后饱和烃部分除了含C12~C27的直链烷烃,还有一些直链烷烃的异构体和环烷烃,芳香烃部分主要是双环、三环、四环芳烃,单环芳烃则完全消失。

| Abstract: | The coal liquefaction recycled oil and the hydrogenation recycled oil were separated into saturated hydrocarbon, aromatic hydrocarbon and polar compounds, respectively using classical column chromatography. The group components were then characterized by 1^H NMR and GC - MS. Results showed that the main components of saturated hydrocarbons of recycled oil were composed of linear hy drocarbon with 12 -27 carbon, whereas those of aromatic hydrocarbons were mainly composed of monoaromatic hydrocarbons and some multi-aromatic hydrocarbons. The main components of saturated hydrocarbons of the recycled oil after 420 ~C hydrogenation were composed of linear hydrocarbon with 12 -27 carbon, and were also composed of some of their isomers and the cycloalkanes. The aromatic hydrocarbons were mainly composed of di-, tri- and tetra-aromatic hydrocarbons, but mono-aromatic hydrocarbon was disappeared completely. |
