Taiheiyo coal extraction experiments with supercritical water (SCW) and SCW-Phenol mixtures were conducted at 400℃ and 25MPa using a semi-continuous apparatus. With increasing the concentration of phenol, the extraction yield increased up to 80wt%-daf. Extraction yield of Yallourn coal extraction shows 80wt%-daf, while that of Adaro coal shows 65wt%-daf with the SCW-PhOH (80wt%) mixtures. Mechanism of the co-solvent reactive extraction was discussed based on the analysis of the products. This suggests the capping effect of phenol to prevent from polymerization of products.
