Mathematical model for simultaneous reaction of carbon monoxide with water, to produce carbon dioxide and hydrogen, and carbon dioxide adsorption with pressure swing operation was formulated with the assumption of finite reaction and adsorption rate. Both reaction and separation performance were investigated with various pressure swing operations modified from Skarstrom cycle by addition of cocurrent purge with carbon dioxide, which was not adsorbed. At 400 ํC, the reaction was enhanced over the equilibrium limit. In addition, high concentration of hydrogen and carbon dioxide were obtained by countercurrent purge with the former and cocurrent purge with the latter, respectively. However, the production rate was lower than that of the conventional plug flow reactor, although the rate could be increased by reduction of the cycle period. The amount fraction of adsorbent in the system improved both reaction performance and purities of hydrogen and carbon dioxide.
