Lithium nitride can be formed in the reaction of lithium metal with nitrogen gas under moderate condition and has attracted attention as a hydrogen storage system; Li3N+2H(2) -%26gt; 2LiH+LiNH2. Li3N is hydrogenated below 300 degrees C under 0.5MPa of H-2, and then LiNH2 is formed as product. Furthermore, the reaction between MNH2 and H-2; MNH2 + H-2 -%26gt; MH + NH3, can proceed below 250 degrees C under 0.5 MPa H-2 flow condition to form MH and NH3. In this study, we proposed and investigated synthesis method of ammonia run under more moderate conditions than those of current Haber-Bosch process by using combination of above two reactions. As the result, it was experimentally clarified that the ammonia synthesis can be operated in realistic reaction rate below 300 degrees C by producing non-equilibrium reaction field under 1.0 MPa H-2 flow condition.
