Hyper-coal (HPC) is an ash-free coal produced by the solvent de-ashing technology. Coal is thermally (360-400℃) extracted into the coal-derived solvent (two ring aromatics). HPC has excellent thermoplasticity and large potential for coke additive to make a strong coke. The yield of HPC depends on the coal solubility. And the solvent must be recovered completely by distillation. So, it is important for HPC process to use a solvent that have not only high solubility of coal but also enough recovery ratio. In this study, we focused on a Washing Oil (WO) that is distillated from coal tar. WO is known to have high solubility of coal. The key compounds for high solubility were cleared, and the recoverability of those compounds was examined.
