To develop a mild chemical desulfurization method without residual chemicals in the treated Hyper-coal, desulfurization behavior was investigated by oxidation using hydrogen peroxide and acetic anhydride at room temperature and by pyrolyzing the treated sample under nitrogen stream. XANES analysis showed that the Hyper-coal contained only thiophenic sulfur and that the thiophenic sulfur changed to sulfone during the oxidation treatment. High removal extent of sulfur with high char yield was achieved by pyrolyzing the oxidized sample prepared at room temperature for 24 hour.
