The iron oxides were prepared by precipitation of aqueous ferric nitrate. The addition of aluminium oxide into iron oxides prevented the sintering of metal iron and/or iron oxides during repeated redox cycles. The optimal calcination temperature for cylindrical pellets preparation was found to be 850 oC. Transport parameters for Fe2O3/Al2O3 and Fe/Al2O3 samples, which can be utilized for optimization of porous structure prepared pellets, were determined by the inverse gas chromatography.
