摘要 为阐明在相同煤化程度下煤中显微组分结构差异特征,运用傅里叶红外光谱仪测试相同煤化程度下煤中不同显微组分的官能团,并采用Origin 9.0软件进行分峰拟合与计算.结果表明:富氢程度参数镜质组高于壳质组、壳质组高于惰质组;脂肪结构参数壳质组高于镜质组、镜质组高于惰质组;芳构化程度镜质组高于惰质组、惰质组高于壳质组;生烃潜力镜质组强于壳质组和惰质组,壳质组的脂肪链较长利于生油,而惰质组的芳构化程度更高于壳质组. In order to clarify the structural difference characteristics of macerals in coal under the same coalification degree.Fourier infrared spectrometer was used to test the functional groups of different macerals in coal under the same coalification degree,and Origin 9.0 was used for peak fitting and calculation.The results showed that the hydrogen-rich parameters of vitrinite were higher than that of exinite and that of exinite were higher than that of inertinite.The fat structure parameters of exinite were higher than that of vitrinite and vitrinite than that of inertinite.The aromatization degree of vitrinite was higher than that of inertinite and inertinite was higher than that of exinite.The results showed that the hydrocarbon generation potential of vitrinite was stronger than that of exinite and inertinite,the fat chain of exinite was longer,and the aromatization degree of inertinite was higher than that of exinite.
