Abstract:
Results of the IR spectroscopic investigation of brown coal from different deposits of Russia and Mongolia are presented. The obtained IR spectroscopic data indicate the presence of complex structures in brown coals containing aliphatic and aromatic hydrocarbon fragments, fragments of oxygen-containing heteroaromatic compounds, as well as oxygen-containing functional groups (carbonyl, hydroxyl, ether). It was found that the aromaticity index fa calculated from the results of IR spectroscopy has a linear correlation with the quality indicators of brown coal - the yield of volatiles (Vdaf), fixed carbon (Cfix ) and the H/C atomic ratio.
