用H_2-CH_4气制备碳化铁的反应过程

THE REACTION PROCESS TO MAKE IRON CARBIDE USING H 2-CH 4 AS REDUCTANT

用Ｈ２－ＣＨ４混合气制备碳化铁实验结果表明：铁矿粉还原生成碳化铁的过程由氧化铁的还原。

The process for making iron carbide from hematite with H 2-CH 4 as reductant has been studied The results show that the formation of iron carbide consists of three steps: reduction of iron ore,cracking of CH 4, carburization of metal Fe,thus providing experimental data for setting up the kinetic model of the reaction
