“…We have earlier [1] synthesized mineral hercynite FeAl 2 O 4 under shock-wave impact on gibbsite under axissymmetric loading [2]. Later [3] we used the same method to grow crystals of mineral gahnite ZnAl 2 O 4 and nonstoichiometric aluminozinc spinel Zn 0.33 Al 2.45 O 4 from amorphous aluminum hydroxide and zinc penetrating the reaction zone from the protective brass wall of the conservation ampoule.…”

Hydrogen and carbon monoxide production from H2O and CO2 is experimentally investigated using a two-step chemical looping process based on redox cycles of iron-alumina mixed oxides. The reduction of Fe3O4 in first endothermic step is followed by splitting of CO2 or H2O in a second exothermic step. The iron-aluminum oxides are more reactive with H2O than with CO2 in the range 650-750 °C. In situ XRD shows that deactivation results from different processes: iron oxide sintering and formation of spinel (FeAl2O4) with lower oxygen storage capacity. However, FeAl2O4 also takes over the role of Al2O3 and mitigates the iron oxide sintering. Deactivation at 650 °C is predominantly governed by sintering, while further loss of activity is due to combined sintering and spinel formation. At 750 °C the spinel formation is more dominant. A mixed oxide of Fe2O3 and Al2O3 with mass ratio of 70:30 was found most active and stable for H2O and CO2 splitting in chemical looping.
