92.石炭の成分および熱分解条件がチャーの構造および反応性に及ぼす影響

抄録

This study was done about the effect of mineral component and pyrolysis condition of coals exerted on the pore-structure and reactivity of chars about 43 kind of standard coal samples. The coal sample was stirred in 1mol/l-HCl for 24 hours, and minerals were removed. Three kinds of chars were prepared under different heating conditions. Though almost the specific surface area of parent coals increased, the true density did not change by demineralization. Yield of chars increased by demineralization. As for reactivity of chars, the difference by the coal kind became small by demineralization. The reactivity of chars were as high as heating rate was fast. There was hardly difference by heating rate though the inter-crystalline and combination stracture of oxygen were observed by using XRD and XPS.
