| Outline of Final Research Achievements |
The application of a membrane reactor capable of effective mass transfer and heat transfer to the combined reaction process of converting ammonia derived from renewable energy into hydrogen and reacting it with CO2 to produce methane was investiagted. As catalysts suitable for reaction conditions in the membrane reactor, Ru/Ba/γ-Al2O3 and Ru/ZrO2 were developed for NH3 decomposition and CO2 methanation, respectively. Simulation analysis was carried out with creating a reaction model in parallel with the experiments for the membrane reactor. It was found that the development of a highly active NH3 decomposition catalyst and superior hydrogen-permeable membrane are the most important issues in aiming to improve the efficiency of cobined reaction process using a hydrogen-permeable membrane reactor.
