摘要
氢基直接还原铁工艺是一种环保、高效的钢铁生产技术,具有广阔的应用前景.在全面介绍氢基直接还原铁工艺的基础上,重点分析了氢基还原气体的成分重整工艺在冶金工业中的应用情况、优缺点和适用性,主要包括水蒸气重整、部分氧化重整、自热重整和二氧化碳重整 4 种重整方法.系统地探讨了中国氢基直接还原铁工艺的探索实践以及面临的机遇挑战,指出焦炉煤气自热重整制取还原气技术将在今后中国氢基直接还原铁中扮演重要角色.
Abstract
The hydrogen-based direct reduced iron(HDRI)process is an environmentally friendly and efficient steel production technology with broad application prospects.On the basis of a comprehensive introduction to the hydrogen based direct reduction iron process,the application,advantages and disadvantages,and applicability of the hydrogen based reduction gas composition reforming process in the metallurgical industry were analyzed,mainly including four reforming methods:steam reforming,partial oxidation reforming,self heating reforming,and carbon dioxide reforming.The exploration and practice of China's hydrogen based direct reduction iron process,as well as the opportunities and challenges it faces were explored.It was pointed out that the technology of coke oven gas self thermal reforming to produce reduction gas would play an important role in China's hydrogen based direct reduction iron in the future.
