55.高温度における各種石炭チャーのCO_2ガス化

抄録

Sixty chars prepared from standard coals and their demineralized coals were gasified in CO_2 up to 1773K in a thermobalance to examine the influence of coal rank and mineral matter and the temperature dependence of reaction rate. In addition, gasification residua obtained at different conversions of the usual reaction system operated at 1173-1773K were characterized in terms of carbon structure and the chemical form of mineral matter (by XRD), surface morphology and the distribution of metals (by SEM EDX), and porous structure (by the BET surface area and pore size distribution measurements).
