Mn-Fe-Al-O mixed spinel oxides as oxygen carrier for chemical looping hydrogen production with CO2 capture

Preparing the oxygen storage material capable of being highly reduced with desirable stability is important to reduce the solid circling rate in a fluidized bed chemical looping reactor. Nevertheless, the high oxygen carrier reduction degree would accelerate sintering. In this work a Mn0.5Fe0.5(FeAl)Ox material is synthesized as the oxygen carrier of chemical looping hydrogen production process. It exhibits a good redox stability during 30...
