摘要
钢铁产业作为工业的重要领域,是能源消耗及CO_(2)排放大户,钢铁工业由化石燃料消耗引起的CO_(2)排放占全国的1/8,占工业的1/4。在碳达峰碳中和这一背景之下,氢冶金等低碳工艺研究热度愈来愈高。煤基氢冶金技术是典型的固态氢冶金技术,也是制-储-用同步实施的氢冶金技术,该技术采用高挥发分煤充分热解和H_(2)O气化C两种途径产出足量H_(2)实现氢冶金过程,此技术符合我国现阶段能源结构,目前已完成氧化球团、钒钛磁铁矿等多种物料的工业试验,稳定取得在窑时间180 min条件下还原球团金属化率85%以上的指标。
As an important field of industry,the steel industry is a major consumer of energy and CO_(2)emissions,the steel industry accounts for 1/8 of the country’s CO_(2)emissions caused by fossil fuel consumption and 1/4 of the industry.In the context of carbon peak and carbon neutrality,the research on low-carbon processes such as hydrogen metallurgy is becoming more and more popular.Coal-based hydrogen metallurgy technology is a typical solid-state hydrogen metallurgy technology,and it is also a hydrogen metallurgy technology implemented simultaneously by production,storage and use,which uses high volatile coal full pyrolysis and H_(2)O gasification C to produce a sufficient amount of H_(2)to achieve hydrogen metallurgy process,this technology is in line with China’s current energy structure,and has completed the industrial test of oxidation pellets,vanadium titanium magnetite and other materials,stable achievement of a metalization rate of over 85%for reduced pellets under kiln time of 180 minutes.
