Performance of a highly reactive impregnated Fe2O 3/Al2O3 oxygen carrier with CH4 and H2S in a 500 Wth CLC unit

A synthetic Fe-based oxygen carrier prepared by impregnation using γ-Al2O3 as support, successfully tested for gas CLC combustion, has been now evaluated with respect to gas combustion in a 500 Wth CLC continuous unit when the fuel, CH4, contained variable amounts of H2S. Full gas combustion was rea...
