• 中文摘要： 本文描述以化學分析方法及1 atm氮氣氣氛下900.degree.C時以熱重分析方法研究煤粉還原鐵礦之動力學。實驗結果顯示在測試過的反應物中燃料煤及澳洲礦的反應性最高。實驗發現煉鐵高爐和/或煉鋼轉爐的礦泥可用加碳還原的方法冶煉出金屬鐵。 K/sub 2/CO/sub 3/、Na/sub 2/CO/sub 3/和 Li/sub 2/CO/sub 3/都是鐵礦還原的良好觸媒,它們的觸媒效應順序是 K/sub 2/CO/sub 3/>Na/sub 2/CO/sub 3/>Li/sub 2/CO/sub 3/。固體樣品中加入助熔劑會降低還原速率。
• 英文摘要： The reduction of iron ore with coal was examined through thermogravimetry analysis under 1 atm nitrogen and 900.degree.C as well as chemical analysis. Experimental results indicated that fuel coal and Australia ore were the most reactive among the coals and ores tested, respectively. It was found that metallic iron could be extracted from sludges of blast furnace and/or basic oxygen furnace by carbothermic reduction. K/sub 2/CO/sub 3/, Na/sub 2/CO/sub 3/ and Li/sub 2/CO/sub 3/ were found to be good catalysts of the reduction and the order is K/sub 2/CO/sub 3/>Na/sub 2/CO/sub 3/>Li/sub 2/CO/ sub 3/. Addition of fluxes to the solid sample may impede the reduction.
