The present invention provides a kind of metal supported catalyst and employs the efficient of this catalyst and generate hydrogen method, and this metal supported catalyst, for ammonia is decomposed into hydrogen and nitrogen, has high-performance and cheap, the most favourable from the viewpoint of resource.A kind of generation hydrogen catalyst, it is for ammonia carrying out catalytic decomposition and generating the catalyst of hydrogen, it is characterised in that by mayenite compound or the interior bag 10 of package oxygen ion 15 cm ‑3 The mayenite compound of individual above conduction electronics or hydride ion makes carrier, is loaded with ammonia decomposition metallic particles at this carrier surface.The ammonia of volume fraction 0.1～100% is continuously fed in the Catalytic Layer being made up of this catalyst, under the reaction pressure of 0.01MPa～1.0MPa and the reaction temperature of 300～800 DEG C, with weight-space velocity (WHSV) 500/mlg ‑1 h ‑1 Reaction carried out above, thus manufacture hydrogen. |
