Abstract:Based on the band absorption of aromatic-CH and aliphatic-CH in the IR spectrum of coals, IR spectroscopy of 18 rank typical Chinese coals has been studied, and the concentration of aromatic-CH and aliphatic-CH in 18 rank coals were determined, which characterize the structure parameter for Chinese coals. The results indicated that the values of H ar /H al and f a are relative to coal rank. Carbon content 85% is the characteristic value of coal.
