17.石炭の軟化溶融性と関連する化学構造のキャラクタリゼーション

抄録

We characterized chemical structure related to the coal plasticity. RuO_4 catalyzed oxidation reaction of coal was performed to analyze the structural features of the coking and non-coking coals, Goonyella and Witbank coals. The results showed several differences in aliphatic portion of coal. We also characterized the released gas and tar fractions and the resulting char fraction during heat-treatment. We discussed the structural diffrence between two coals based on the above results.
