Abstract

The structural features of inertinite components in coal are studied by IR and Raman spectroscopy. Five samples of coal fractions (density 1.40–1.45 g/cm³) from coal of different metamorphic development are studied; their vitrinite reflection coefficients are 0.85–2.10%. Analysis of the Raman spectra indicates that the width of the G-band is less for inertinite samples of greater metamorphic development, on account of greater condensation of the aromatic rings and shortening of the alkyl chains. That agrees with the IR spectral data.

通过红外和拉曼光谱研究煤炭的惰质组份

摘要

通过红外光谱和拉曼光谱研究了煤中惰质组分的结构特征。研究了五种不同变质发育煤的煤级分样品（密度1.40-1.45 g / cm ³）；它们的镜质体反射系数为0.85–2.10％。拉曼光谱的分析表明，由于芳环的缩合更大和烷基链的缩短，对于较大变质发展的惰质样品，G谱带的宽度较小。这与红外光谱数据一致。
