Abstract
A lithium hydride activation method includes: a nitrification treatment process of reacting lithium hydride with a nitride and therefore forming a chemical compound layer stable to the nitride, on a surface of the lithium hydride; and a particle size reduction process of reducing a particle size of the lithium hydride provided with the chemical compound layer by a mechanical pulverization treatment after the nitrification treatment process is performed. A hydrogen generation method includes generating hydrogen by reacting ammonia with the lithium hydride activated by the activation method.
Claims5
A hydrogen generation method comprising:
- performing a nitrification treatment of reacting lithium hydride with a nitrogen atom containing compound and therefore forming a chemical compound layer stable to the nitrogen atom containing compound, on a surface of the lithium hydride;
- reducing a particle size of the lithium hydride provided with the chemical compound layer by a mechanical pulverization treatment after the nitrification treatment is performed to produce a pulverized lithium hydride;
- and
- generating hydrogen by reacting ammonia and the pulverized lithium hydride;
- wherein the lithium hydride is not being pulverized by a mechanical pulverization treatment while generating hydrogen.
