| 摘 要： | 针对褐煤的结构特点（无定型碳结构和高氧含量等）,介绍了其各种含氧官能团和碳结构的分析方法,对化学滴定法、傅里叶变换红外光谱（FT-IR）和X-射线衍射（XRD）光谱分析方法进行了说明和比较;重点解释了一种使用傅里叶变换拉曼光谱（FT-Raman）半定量分析褐煤及其衍生半焦炭结构的方法。根据褐煤及其半焦炭的碳结构特征,Raman光谱被解析为具有一定物理意义的10个子峰,试验证明该方法能够有效地半定量分析无定型碳结构中的分子结构信息。

| Abstract: | According to the structure features(amorphous carbon structure,high oxygen content and others) of the lignite,the paper introduced the analysis method of different oxygen functional group and carbon structure.The paper had an explanation and comparison on the chemical titration,Fourier infrared spectrum and X-ray diffraction spectrum analysis method.The paper in detail explained a FT-Raman semi-quantitative method to analyze the lignite and the derived semi-coke structure.According to the carbon structure features of the lignite and the semi-coke,the Raman spectrum was analyzed as 10 sub-peaks with certain physical meanings and the experiment showed that the method could effectively semi-quantitatively analyze the molecular structure information in the amorphous carbon structure. |
