30.Ca担持チャーのCO_2ガス化に及ぼす共存ガスの影響

抄録

Gasification behavior of Ca-loaded char in mixture of CO_2 and H_2 was investigated with thermogravimetry. The chemical form of Cacompound on char surface under reaction conditions was determined with high temperature X-ray diffraction (HT-XRD). Furthermore the effect of H_2 on the formation of surface oxygen complexes during gasification was analyzed with transient kinetics. From these results, the mechanism of H_2 inhibition on CO_2 gasification of Ca-loaded char was discussed.
