Ashless coal (HyperCoal) was produced through solvent extraction of coals at 360℃. An attempt at searching a powerful solvent to produce HyperCoal more efficiently was made. Some polar constituents fractionated from crude methyl-naphthalene oil (CMNO) were used as the extraction solvent. It was found that one constituent gave high extraction yields of 63-73wt% (daf) for Wyodak Anderson subbituminous coal. The reason for the high yields was explained by effect of indole contained in the fractionated solvent.
