The process of methane steam reforming is introduced in this paper. The status and research progress of catalyst carrier,catalyst active component and catalyst auxiliary for methane reforming hydrogen production technology are reviewed. The reaction mechanism and the progress of intrinsic kinetics of methane steam reforming reaction are explained. The present situation and research progress of traditional methane reforming hydrogen production reactors,and the research and application status of new hydrogen production reactors are reviewed. HTCR reactor developed by Topsóe company can effectively reduce the consumption rate of raw materials and fuels,which has been used abroad for decades. Extension-type reactor developed by Dalian Petrochemical Research Institute can utilize effectively high-grade heat and reduce energy consumption of hydrogen production by about 10%.
