Abstract: Dry Reforming of Methane (DRM) technology is one of the technologies for CO2 resource utilization, the application of Ni-based catalyst can reduce the energy of DRM reaction. The research analyzes the reaction mechanism of Ni-based catalysts during the DRM reaction process, as well as the cause of the reasons for the loss of Ni-based catalysts such as carbon, metal activated component sintering, sulfur poisoning, etc. This paper describes the research results of currently improving the catalytic performance of Ni-based catalysts, and provides a research direction for the future development of Ni-based catalysts with high stability, selectivity, activity, and resistance to carbon deposition. And it provides theoretical guidance and research basis for the industrial application of Ni-based catalyst in DRM.
