Carbon emission reduction in the iron and steel industry is critical for achieving China′s carbon neutral goal. This paper systematically reviews the research and application progress of various carbon capture technologies. The characteristics of carbon emissions in the iron and steel industry are summarized, highlighting blast furnace as the main source, contributing roughly 30% of the total CO_2 emissions in the industry. Carbon capture technologies in the iron and steel industry mainly include organic amine absorption, ammonia water absorption, pressure swing adsorption, and steel slag mineralization. However, there are only a few small-scale applications in practice. Additionally, the research progressof carbon capture materials, such as new organic amine absorbents and modified molecular sieve materials, is systematically introduced. Future studies should focus on CO_2 capture from blast furnace gas and hot blast furnace flue gas. Moreover, research on phase-change absorption systems and catalytic-assisted regeneration systems should be reinforced to address issues related to the balance between phase separation and absorber viscosity, as well as catalyst stability. This will ultimately facilitate their combined application with improved efficiency and reduced energy consumption. Furthermore, future research should focus on integrated technologies of CO_2 capture and utilization, including flue gas-steelslag direct mineralization and combined capture and mineralization processes.
