Abstract：Based on the principle of hydrogen production reaction from CaO carbonation reaction enhancement of steam methane reforming, the influences of two main factors including the performance of the CaO-based adsorbents and reaction conditions on the reaction sorption enhanced reforming (ReSER) process of methane were summarized. Furthermore, the research progress about industrial reactor types and processes in the hydrogen production of ReSER was reviewed. It was concluded that the adsorption performance of CaO-based adsorbent was the fundamental factor affecting the coupling enhanced reaction, and the durability of its adsorption capacity was the key to realize the industrialization of ReSER technology, and the CH4 conversion and H2 concentration in the hydrogen production of ReSER were directly affected by the reaction conditions. Actually, the enhanced reaction effect and economic cost must be comprehensively considered for the selection of actual reaction conditions. The circulating fluidized bed reactor and the corresponding reaction system were selected to be a feasible industrial process according to the characteristics of the ReSER. The hydrogen production technology of ReSER has great potential for industrial application due to the advantages of the reaction itself.
