Preliminary Exploration of Coal Oxidation in Supercritical Water
煤炭在超临界水中氧化的初步实验

The oxidation of coal in supercritical water was investigated by using O2 decomposed in situ from H2O2 as the oxidant. The results indicated that the sulfur and nitrogen contained in coal were gradually converted into SO42 and N2 respectively by oxidation in the supercritical water medium. The coal oxidation became faster with higher reaction temperature and higher concentration of H2O2.
