【Abstract】 In recent years, the application of CO₂ capture technology in the steel industry and its future development were reviewed. The current status of global steel industry production and carbon emissions was briefly described, and several types of typical CO₂ capture processes were introduced. It pointed out that carbon capture and utilization（CCU） technology can provide a promising path for reducing CO₂ emissions in the steel industry. The process principle, development prospect, and application trend of typical CO₂ capture technology were analyzed. Finally, combining the three technologies of flue gas CO₂ capture after combustion, blast furnace top gas cycle CO₂ capture, carbon capture, and bioenergy with carbon capture and storage（BECCS）, the important role of carbon capture technology in the steel production process has prospected.更多还原
