48.石炭チャーガス化時の微細構造に対する鉱物質の影響(石炭利用における科学と工学の接点)

抄録

In order to investigate the effect of mineral matter on micro-sturctural changes of coal char during gasification, raw coal and acid-treated coal were pyrolized and the chars were observed by fixed-point observation using TEM. And, micro-sturctural changes of carbonaceous material included in coal char during heat-treatment were also observed with similar technique.
