| 摘 要： | 本文提出了以甲醇作溶剂用荧光光谱分析煤短接触液化产品的方法。对煤的短接触液化产品用不同极性的溶剂洗提得到9个级分,从9个级分中鉴定出25种组分。为了与煤焦油比较,用同样的方法和操作程序测定了煤焦油,鉴定出28个组分。本文还用液相色谱分析测定了煤短接触液化产品的氯仿洗提级分,所得结果与荧光光谱分析所得结果一致,证实了该方法的可靠性。 |

| Abstract: | In this paper the procedure and the result of analysing the coal liquid which was formed in short Contact time liquefaction by fluorescence spectroscopy were described. The identification was based on fluorescence wave-lengths of the components in the coal liquid. The coal liquid was processed by sequential elution with 9 kinds of solvents in silica gel column. Nine fractions of coal liquid were obtained for further study. Twenty five components were identified in the fractions. Twenty eight components in coal tar were identified by the same method to compare with those in the coal liquid. One of the fractions (chloroform as eluent) of the coal liquid was analysed by HPLC to check the result from fluorescence spectroscopy. |
