چکیده انگلیسی
The samples Mg-10Â wt.% (Fe2O3, Ni, MnO) was prepared by mechanical grinding under H2 (reactive mechanical grinding) under the optimum conditions, studied previously, for the preparation of the sample Mg-10Â wt.% Fe2O3 using purchased Fe2O3. The sample Mg-10Â wt.% (Fe2O3, Ni, MnO) as milled absorbed 4.15Â wt.% hydrogen at 593Â K under 12Â bar H2 for 60Â min. Its activation was accomplished after two hydriding-dehydriding cycles. The activated sample absorbed 4.02Â wt.% hydrogen at 593Â K, 12Â bar H2 for 60Â min desorbed 3.03Â wt.% hydrogen at 603Â K, 1.0Â bar H2. Hydrogen-storage capacity was 5.34Â wt.% under 12Â bar at 593Â K (from P-C-T curve). The equilibrium plateau pressure is about 1.5Â bar H2. Mg-10Â wt.% (Fe2O3, Ni, MnO) has lower hydriding rate than Mg-10Â wt.% Fe2O3 by spray conversion, but it has higher dehydriding rate than Mg-10Â wt.% MnO and Mg-10Â wt.% Fe2O3 by spray conversion.
