We have investigated the development of coal liquefaction process through partial oxidation in supercritical water. In this study, we conducted hydrodenitrogenation of calbazole via water-gas shift reaction in supercritical water and partial oxidation of n-hexadecane in supercritical water using a tube bomb batch reactor. For hydrodenitrogenation of calbazole, the yield of tetrahydrocarbazole and denitrogenated compounds at 0.3g/cm^3 of water density was higher than that at lower water density, except for 0.05g/cm^3 of water density. The yield of unknown product, which was seemed to be higher molecular weight compound, was suppressed in supercritical water. For partial oxidation of n-hexadecane in supercritical water, the relative amount of oxygenated compounds, which were CO, aldehydes, and ketones, increased with increasing water density. The relative amount of n-alkane also increased with increasing water density.
