Activation By High Temperature Reduction of Ru Catalyst Supported on Rare Earth Oxide for Ammonia Synthesis

Yuta OguraKatsutoshi NagaokaKatsutoshi Sato

Ammonia is an important chemical feedstock, and more than 80% of the synthesized ammonia is used to produce fertilizer. Ammonia is also being considered as an energy carrier and hydrogen source (1) because it has a high energy density (12.8 GJ m-3) and a high hydrogen content (17.6 wt%), (2) because infrastructure for ammonia storage and transportation is already established, and (3) because carbon dioxide is not emitted when ammonia is decomposed to produce hydrogen. If ammonia could be efficiently produced from a renewable energy source, such as solar or wind energy, problems related to the global energy crisis could…

Carbon-Free H2 Production from NH3 Triggered at Ambient Temperature with Oxide Supported Ru Catalysts

Katsutoshi NagaokaKatsutoshi SatoYuta Ogura

Hydrogen produced from renewable energy has received a lot of attentions as a clean energy and development of a hydrogen storage and transportation system using hydrogen carrier has been greatly demanded. Among different kinds of hydrogen carrier, NH3 is regarded as one of the promising candidates, due to high energy density, high hydrogen capacity, and ease of liquification at room temperature. Furthermore, a carbon-free hydrogen storage and transportation system could be realized by using NH3 as hydrogen carrier. In this system, hydrogen produced from NH3 is used in engines, fuel cells, and turbines. However, use of NH3 as a hydrogen…
