Reduction and Gasification Characteristics of A Unique Iron Ore/carbon Composite prepared from Robe River and a Coal Tar Vacuum Residue
ピソライト鉄鉱石と重質炭素を混合300℃以上に加熱すると，ピソライト鉄鉱石の脱水で生成した微細細孔内に炭素が生成する。この炭素は鉄鉱石を800℃以下で鉄鉱石を還元すると同時に，炭素は同程度の温度でCO2で迅速にガス化される。TG-DSCを用いてこれらのユニークな反応に加えて水素による還元の反応エンタルピーと活性化エネルギーを測定した。
