Abstract
Several low-rank coals were hydrothermally treated at 200-350℃ in an autoclave. The raw coal and treated coals were analyzed by FTIR with a curve-fitting method. The aromaticity and methyl/methylene ratio somewhat increased due to the treatment, while the content of carboxyl group greatly decreased. Also, thermal properties of the treated coals were examined by use of TG-DTA.
