摘要/Abstract

摘要： 转炉炼钢过程中排放的高温熔融钢渣富含大量的热能和化学能，通过其与水蒸气反应制取H2，可以实现冶金过程能量的有效回收利用. 本文对熔融钢渣与水蒸气反应是否有H2生成进行了实验验证，并利用热力学计算软件FactSage分析了1600℃下钢渣成分对制氢反应的影响. 结果表明：反应初期H2的离子强度由0 A迅速上升到8.4×10-9 A，反应后钢渣质量增加了0.091 g；增加渣中FeO含量、提高钢渣碱度(W(CaO)/W(SiO2))均有利于获得更多的H2，渣中MnO含量的变化对制氢反应影响不大，而渣中Al2O3含量的增加则抑制了H2的产生.

Abstract: Molten steelmaking slag produced during converter steel-making process contains a large amount of heat energy and chemical energy. It can be used to react with water vapor for H2 production to realize the effective recycling for the energy in metallurgical process. In this paper, the generation of H2 was proved by experiment and the effects of slag compositions on H2 production were analyzed by FactSage. It turns out that, the ion current of H2 increased from 0 A to 8.4×10-9A immediately at the begining of reaction and the weight of slag increased by 0.091 g during reaction. FeO content and the increasement of slag basicity (W(CaO)/W(SiO2)) are beneficial to obtain more H2. The change of MnO content in slag has little effect on H2 production and the amount of Al2O3 has negative effect on H2 production.
