摘要
在"双碳"目标与"双高"限制的双重挑战下,火法冶金领域正面临能耗与碳排放的双重压力,对清洁能源的需求愈发迫切.氢能,作为一种可再生清洁能源,为火法冶金带来了节能低碳、绿色转型的新曙光.基于CH4-H2 体系的氢还原技术,凭借其优良的还原能力和低碳无污染的特性,已成为冶金领域研究的热点.阐述了CH4-H2体系的还原热力学与动力学原理,以及国内外相关技术及研究进展,总结了该技术在还原金属矿物(铁、钛、镍、锌、钴、铬、锰)方面的研究成果与发展方向,并针对尚未解决的问题进行了系统分析.基于CH4-H2 体系的氢还原技术有巨大的应用潜力,这些探讨将有助于推动该技术的进一步发展.
Abstract
Under the dual challenges posed by the"dual carbon"goals and"double high"restrictions,the field of pyrometallurgy is experiencing significant pressures related to energy consumption and car-bon emissions,thereby heightening the urgent need for clean energy.Hydrogen energy,as a renewable clean energy source,offers a new dawn for pyrometallurgy in terms of energy-saving,low-carbon,and green transformation.Hydrogen reduction technology based on the CH4-H2 system,with its excellent re-duction capability and low-carbon,pollution-free characteristics,has emerged as a research hotspot in the metallurgical field.This paper elucidates the reduction thermodynamics and kinetics principles of the CH4-H2 system,systematically reviews the relevant domestic and international technologies and re-search progress,summarizes the research achievements and development directions of this technology in the reduction of metallic minerals(iron,titanium,nickel,zinc,cobalt,chromium,and manganese),and conducts a systematic analysis of the unresolved issues.The hydrogen reduction technology based on the CH4-H2 system holds immense application potential,and these discussions will contribute to ad-vancing the further development of this technology.
