Abstract：This paper discusses the potential of synergistic application of methane dry reforming(CH4-DRM)and carbonate decomposition technology for CO2 emission reduction in the cement industry and its industrial application prospects.The basic principle and thermodynamic characteristics of CH4-DRM reaction are introduced,and its key role in CO2 resource utilization is analyzed.The research progress of related catalyst design and reaction condition optimization is also summarized.For in-situ CO2 reduction via carbonate decomposition,the thermal efficiency advantages and the industrial coupling approaches with CH4-DRM are discussed,and the feasibility of industrial application is evaluated.Finally,the future research directions are proposed based on clarifying reaction mechanism,process integration,catalyst optimization and large-scale utilization evaluation,providing theoretical support and technical guidance for the low-carbon transformation of the cement industry.
