PSA (pressure swing adsorption) was applied to the regeneration of adsorbent in simultaneous operations of reaction and separation. Dehydrogenation of cyclohexane was used as the model reaction. The hydrogenstorage alloy (CaNi<SUB>5</SUB>) was suitable to the adsorbent. The reaction rate was of 0.8 th order with respect to cyclohexane concentration. The reaction temperatures were 150 and 190°C. Conversion in the reactor with hydrogen storage alloy greatly exceeded equilibrium and then turned gradually to equilibrium. The alloy could be regenerated by helium purge. High conversions were obtained by periodic operations of reaction and purge. The yields of product in one cycle were increased by increasing the weight of alloy.
