초록
Chemical looping hydrogen production (CLHP) is an attractive technology for H2 production due to its ability to produce H2and capture CO2 from fossil fuels simultaneously. In this paper, we present MgFe2O4 as an oxygen carrier material with highefficiency, low cost, and stable properties for CLHP. The redox reactions occurred reversibly in the fuel, steam, and air reactoras MgFe2O4→MgO/Fe, MgO/Fe→MgO/Fe3O4, and MgO/Fe3O4→MgFe2O4, respectively. The oxygen transfer capacities ofMgFe2O4 for 5% H2/N2 and 5% CO/N2 gases were about 23 wt% at 900 °C. Both the oxygen transfer capacity and rate werewell maintained during 10 redox cycles at 900 °C. No phase changes or agglomeration occurred as the redox cycle numberincreased. Similarly, MgFe2O4 did not exhibit significant degradation in its total amount or maximum rate of H2 productionduring four redox cycles. The average calculated amount of H2 production for MgFe2O4 was 2,806 L/day per unit mass (kg).
Abstract
Chemical looping hydrogen production (CLHP) is an attractive technology for H2 production due to its ability to produce H2and capture CO2 from fossil fuels simultaneously. In this paper, we present MgFe2O4 as an oxygen carrier material with highefficiency, low cost, and stable properties for CLHP. The redox reactions occurred reversibly in the fuel, steam, and air reactoras MgFe2O4→MgO/Fe, MgO/Fe→MgO/Fe3O4, and MgO/Fe3O4→MgFe2O4, respectively. The oxygen transfer capacities ofMgFe2O4 for 5% H2/N2 and 5% CO/N2 gases were about 23 wt% at 900 °C. Both the oxygen transfer capacity and rate werewell maintained during 10 redox cycles at 900 °C. No phase changes or agglomeration occurred as the redox cycle numberincreased. Similarly, MgFe2O4 did not exhibit significant degradation in its total amount or maximum rate of H2 productionduring four redox cycles.
