Effects of polar additives on the thermal extraction yields with organic solvents were investigated. Dimethylnaphthalene (DMN-T) containing 1.6% nitrogen gave about 70% extraction yields for UF and IL coals. This can be the result of solvent relaxation by the nitrogen-containing compounds, in addition to thermal relaxation of coal molecules by heating. However, the quantities of remaining solvent and ash in the HyperCoal were remarkable, compared to the case of Light Cycle Oil (LCO), which is a non-polar solvent. When some polar compounds were added by 1% to the LCO, the increase in extraction yield was small, while, in the case of 10% addition, it increased by 7% and the remaining solvent and ash were quite smaller than those obtained from the DMN-T extraction.
