| Outline of Final Research Achievements |
Reforming reactions of bioethanol and biogas to hydrogen and carbon monoxide are industrially important, using Ni catalyst. Side reactions, however, cause carbon deposition and inactivation of the catalyst. In the study, catalyst supports with fast oxide-ion conductivity, which were expected to have resistance to carbon deposition. According to the results, it was found that LaGaO3-, LaAlO3- and BaTiO3-based oxides functioned as inhibitors, depressing carbon deposition. The function was likely due to the mobile oxide ions in the catalyst supports.
