Abstract

The most important Colombian coals were studied using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) Spectroscopy. The ATR-FTIR spectra were used to obtain structural parameters of coal and correlating these structural parameters with the rank of the coal. The structural parameters, methylene-methyl ratio (CH$_{2}$/CH$_{3})$, aromaticity factor (f$_{a})$, aliphatic-aromatic ratio (H$_{al}$/H$_{ar})$ were determined directly from the ATR-FTIR spectra and f$_{a}$ was evaluated from spectra data and an elemental analysis in coals studied here. The aliphatic and aromatic regions were considered between 3000 - 2800 cm$^{ - 1}$ and 912 - 670 cm$^{ - 1}$, respectively.
