 note = {Cyclic operation experiments of catalytic cyclohexane dehydrogenation / carbon dioxide hydrogenation were carried out using LaNi_5 Particles as a catalyst and as a hydrogen reservoir. The final purpose of this study is to develop a membrane separation-type catalytic reactor. Five kinds of LaNi_5 particles ranging from 10 to 725 μm in mean diameter were used. After a 30 minute
activation of LaNi_5 using hydrogen at 673 K, carbon dioxide and cyclohexane were allowed to flow through the LaNi_5 particle bed for each 30 minutes at 673 K, alternatively. The cycle recurred 4 times. The total time of the whole operation, therefore, was 4 hours. In the case of cyclohexane feed, cyclohexene, benzene and hydrogen were detected as products. Cyclohexane conversion increased with decreasing the mean diameter of LaNi_5, i.e., with increasing external surface area per unit mass of alloy. In the case of carbon dioxide feed, carbon monoxide was formed. Hydrogen also was detected in the outlet gas. Carbon monoxide yield also increased with decreasing the mean diameter of LaNi_5. To determine the amount of hydrogen in LaNi_5 available for carbon dioxide reduction, carbon dioxide was allowed to flow through the alloy bed until the carbon monoxide yield reached zero at 643, 653, 663 and 673 K, respectively.},
