Claims

I Claim:

1. A method of co-producing hydrogen and metal, the method comprising the steps of:

- reacting Magnesium hydride and a compound A, selected from a group including metal oxide and metal sulphide, in a fluidized bed reactor wherein the reaction is performed in sealed inert gas flushed reaction chamber and heated between 25°C and 1000°C;

- collecting the hydrogen gas evolved;

- collecting and separating the metal and MgO thus produced.

2. The method of co-producing hydrogen and metal as claimed in claim 1, wherein the compound A is at least one from the group consisting of H2O,

Si02, Al203,Cr203, Ti02, Sn02, Zr02, CuO, CuS, CuFeS2, ZnO, WO3, Ta205, Mn02,Cs2Cr207 and CsOH.

3. A method of co-producing hydrogen and metal, the method comprising the steps of:

- reacting of a metal P and metal oxide Q with water in a fluidized bed reactor in a sealed inert gas flushed reaction chamber and heating between 25°C and 1000°C;

- collecting the hydrogen gas evolved;

- collecting and separating the metal and MgO thus produced.

4. The method of coproducing hydrogen and metal as claimed in claim 3, wherein the metal P is at least one of Magnesium, Calcium, Aluminium or Silicon.

5. The method of coproducing hydrogen and metal as claimed in claim 4, wherein the metal oxide Q is selected from a group consisting of Si02, Cr203, Ti02, Sn02, Zr02, CuO, ZnO, WO3, Ta2Os, Cs2Cr207 or CsOH.

6. The method of producing hydrogen as claimed in claim 1 which is carbon emission free and is highly economical.

7. The method of producing hydrogen as claimed in claim 4 which is carbon emission free and is highly economical.
