摘要
为了寻找一条强化氢还原金属氧化物反应的有效途径,利用直流脉冲电场下产生的非平衡等离子态的氢对CuO进行还原实验,并与相应条件下用分子态氢还原CuO的实验结果进行了对比。结果表明:在体系压力为450Pa、反应温度为200℃、反应时间为30min条件下,分子态的氢不能还原CuO,而等离子态的氢则可将CuO还原成金属铜。这表明把分子态氢转变成等离子态氢后能强化氢还原金属氧化物的能力。
For finding a efficiency approach to enhance the reduction ability of hydrongen, the reduction of CuO by as-nonequilibrium plasma hydrogen produced by a DC pulsed glow discharge was studied, and the comparisons with the reduction of CuO by as-molecular hydrogen was done. Under the condition of a pressure of 450 Pa and a temperature of 200 ℃, the reduction time is from 10 min to 60 min, the experimental results show that CuO was reduced with plasma hydrogen to metal copper, while it was unreducible by as-molecular hydrogen. All these results indicated that the reduction ability of hydrogen is enhanced by transforming as-molecular H_2 to as-plasma hydrogen.
