This paper summarizes recent progress in the study of the separation enhanced reaction process (SERP) for the production of hydrogen from the steam reforming of methane (MSR) in a single unit operation. This process employs a packed column containing an admixture of a catalyst and an adsorbent or acceptor capable of selectively removing carbon dioxide as a reaction by-product from the reaction zone. The present status of research regarding various factors influencing the adsorbent and acceptor, respectively, are discussed in detail. The main advantages and disadvantages of SERP-MSR compared with the more conventional MSR process are advanced.
