摘要

摘要: 我国是CO₂排放大国,水泥、钢铁、化工等高碳排放行业节能降碳势在必行。钢渣碳酸化是利用冶金固废转炉渣吸收捕集温室气体CO₂的低碳技术,既可实现CO₂捕集消纳,还可通过碳酸化反应实现钢渣的安定化处理,提升钢渣建材制品性能。因此,钢渣碳酸化技术应用前景较为广阔。基于此,详细介绍了国内外钢渣碳酸化技术研究、发展及存在问题,进一步分析了前沿的微生物碳酸化钢渣技术及其应用情况。提出应加强开发低投入、高成效的碳酸化效率提升技术,如钢渣微生物碳酸化技术,在保证碳酸化钢渣凝胶特性的同时,同步提升钢渣碳酸化效率和速率,以具有实现钢渣资源化利用和碳减排的重大意义。

Abstract: China is a major emitter of carbon dioxide, therefore, energy conservation and carbon reduction in high carbon emitting industries such as cement, steel, and chemicals are imperative. Steel slag carbonation is a low-carbon technology that utilizes metallurgical solid waste converter slag to absorb and capture greenhouse gas carbon dioxide. It can not only achieve carbon dioxide capture and consumption, but also stabilize steel slag through carbonation reaction, improving the performance of steel slag building materials. Therefore, the application prospects of steel slag carbonation technology are relatively broad. Based on this, a detailed introduction was given to the research, development, and existing problems of steel slag carbonation technology at home and abroad. Further analysis was conducted on the cutting-edge microbial carbonation technology for steel slag and its application. It is proposed to strengthen the development of low input and high effect carbonation efficiency improvement technology, such as steel slag microbial carbonation technology, to simultaneously improve the efficiency and rate of steel slag carbonation while ensuring the gel characteristics of carbonated steel slag, which will help to realize the resource utilization of steel slag and carbon reduction.
