煩雑であるうえに、処理費用も高価とな、る。In the metal hydride device as described above, hydrogen absorption and release reactions by the metal hydride are usually performed in a container filled with the metal hydride. For example, when a metal hydride is directly taken out into the air from an active state in a hydrogen atmosphere, the surface of the metal hydride is rapidly oxidized, generating heat and igniting. Therefore, for example, when disposing of a container filled with metal hydride, it is dangerous to take out the metal hydride inside the container into the air without performing any inactivation treatment. ,
Conventionally, when removing metal hydrides from a container, hydrogen is removed from the container filled with metal hydrides under reduced pressure, and then water is poured into the container to prevent the metal hydride from generating heat. However, such a method is not only complicated, but also expensive.

An object of the present invention is to provide a metal hydride container equipped with the following.

The container is characterized by comprising a mechanism for communicating the container and the small chamber by an operation from outside the container.

性化とは、上記のように活性な金属水素化物からその活
性を失わしめることをいう。In the present invention, the active metal hydride typically refers to a metal hydride that is in a hydrogen atmosphere and has the ability to absorb and release hydrogen. For example, when a metal hydride is packed in a closed container and the metal hydride is active, as shown by the solid line in Figure 3,
By filling the container with hydrogen under pressure, the metal hydride absorbs this hydrogen, so the hydrogen pressure in the container decreases. Also, if the pressure inside the container is reduced from this situation,
Metal hydrides release hydrogen. On the other hand, as shown by the broken line in Figure 3, inert metal hydrides do not absorb hydrogen even if hydrogen is filled into the container under pressure, so the hydrogen pressure inside the container does not change. . Inactivation of a metal hydride means to make an active metal hydride lose its activity as described above.

せても、金属水素化物は十分に不活性化されない。In the present invention, as described above, when the inside of the container is communicated with the small chamber and the active metal hydride is brought into contact with a halogen-containing substance to be inactivated, the total amount of hydrogen that the metal hydride can store is Taking into account the nature of the halogen-containing material, the amount of its filling in the chamber is chosen so that it is in contact with about 0.001% by volume or more of the halogen-containing material. Approximately 0.0% of the total amount of hydrogen that metal hydrides can store in halogen-containing substances.
Contacting the metal hydride in an amount less than 0.001% by volume does not sufficiently inactivate the metal hydride.

Restore activity. On the other hand, when a metal hydride is inactivated by contacting with a halogen-containing substance of about 1% or more by volume based on the total amount of hydrogen it can store, the metal hydride becomes almost irreversibly inert. Usually, in order to be
Even with subsequent activation processing, the activity is not restored.

The metal hydride is similarly deactivated by allowing the metal hydride to pass through. Metal hydrides inactivated in this way do not generate heat or ignite even when taken out into the air.
