| Popis: |
The sulfur tolerance over palladium supported on pure alumina and on alumina modified with barium of catalytic combustion of methane is investigated. Characterization of the catalysts is performed by, XRD and H2-TPR techniques. Barium nitrate as the precursor to the formation of Ba(NO2)2species can inhibit the SO2and SO3overflow from Al2(SO3)3and Al2(SO4)3sulfate to the adjacent PdO. Ba content on the performance of the catalyst resistance to sulfur poisoning has important implications. 0.7% Ba-1% Pd/Al2O3catalyst resistance to sulfur poisoning property is close to that of high load capacity 5% Pd/Al2O3catalyst. |
