Claims
- 1. A process for the production of a magnesium-containing metal granulate which is adaptable for the storage of hydrogen, comprising adding a catalytically effective amount of iron or a ferriferous alloy to molten magnesium or a molten magnesium-containing alloy to obtain a ferriferous magnesium or a ferriferous magnesium alloy and granulating said ferriferous magnesium or ferriferous magnesium alloy thereby forming a catalytically active surface upon said granulated ferriferous magnesium or ferriferous magnesium alloy, said catalytically active surface promoting the storage of hydrogen by said granulated ferriferous magnesium or ferriferous magnesium alloy.
- 2. Process as claimed in claim 1, comprising adding about 1 to 20% by weight of iron to the magnesium or magnesium-containing alloy.
- 3. Process as claimed in claim 1 or 2, comprising smelting the magnesium together with fine iron particles; homogeneously distributing the iron particles in the magnesium smelt and maintaining said homogeneous distribution during solidification of the smelt; and granulating the solidified material.
- 4. Process as claimed in claim 1 and 2, comprising smelting magnesium together with fine iron particles; homogeneously distributing the iron particles in magnesium smelt; and granulating the smelt through spraying.
- 5. Process as claimed in claim 1, comprising smelting said material in a crucible formed of iron or a ferriferous alloy.
- 6. Process as claimed in claim 1, comprising smelting the magnesium or magnesium containing alloy together with sponge iron or powdered iron having particle sizes equal to or smaller than 100 .mu.m.
- 7. Process according to claim 1, comprising effecting said smelting in a hydrogen atmosphere.
- 8. A process for the production of a magnesium-containing metal granulate which is adaptable for the storage of hydrogen, comprising adding a catalytically effective amount of powdered iron or a powdered ferriferous iron alloy to powdered magnesium or a powdered magnesium-containing alloy; sintering the formed mixture and granulating the sintered mixture to thereby obtain a granulated material suitable for promoting the storage of hydrogen.
- 9. Process as claimed in claim 8, comprising sintering the mixture at less than 100.degree. C. below the smelting temperature of the magnesium.
- 10. Process as claimed in claim 8 or 9, comprising utilizing magnesium-containing MgH.sub.2 powder.
- 11. Process as claimed in claim 1, comprising activating the metal granulate in a hydrogen atmosphere at 1.5 MPa and at a temperature of between 350.degree. and 450.degree. C.
- 12. Process as claimed in claim 11, comprising activating said metal granulate at a temperature of 400.degree. C.
