Illinois No.6 coal was treated with a mixed solvent of water and cyclohexanol at 300-350℃ and 5.6-6.1MPa. The solvent treated coals were prepared by two methods, that is, explosive treatment and normal treatment in which high temperature and pressure are reduced immediately and gradually, respectively. Yield of the treated coal by the explosive treatment was higher than that by the normal treatment. This suggests the suppression of pyrolysis by explosive treatment. The properties of the treated coals were characterized by elemental analysis, CO_2 adsorption, SEM, and FT-IR measurements.
