Indirect reduction reaction

Japanese: 間接還元反応 - かんせつかんげんはんのう
Indirect reduction reaction

…In other words, the iron oxide with the highest oxidation degree in iron ore is hematite Fe 2 O 3 , which becomes magnetite Fe 3 O 4 and wustite FeO, and then becomes iron Fe. 3Fe 2 O 3 (solid) + CO (gas) - → 2Fe 3 O 4 (solid) + CO 2 (gas) Fe 3 O 4 (solid) + CO (gas) - → 3FeO (solid) + CO 2 (gas) FeO (solid) + CO (gas) - → Fe (solid) + CO 2 (gas) This reduction reaction of iron oxide by CO is called an indirect reduction reaction. Iron ore that has reached 1000-1200°C has almost completely changed into FeO and Fe. …

…つまり,鉄鉱石中の最も酸化度の高い酸化鉄はヘマタイトFe2O3であり,これがマグネタイトFe3O4,ウスタイトFeOを経て鉄Feになる。 3Fe2O3(固)+CO(気)  ―→2Fe3O4(固)+CO2(気) Fe3O4(固)+CO(気)  ―→3FeO(固)+CO2(気) FeO(固)+CO(気)―→Fe(固)+CO2(気)このCOによる酸化鉄の還元反応を間接還元反応と呼ぶ。1000~1200℃に達した鉄鉱石はほぼFeOとFeに変化している。…
