| 英文摘要 | Fe-substituted hexaaluminate (BaFexAl12-xO19-delta) was prepared with co-precipitation method followed by hydrothermal treatment. The XRD and SEM results indicated that no hexaaluminate phase was formed when calcined below 1000 degreesC, and hexaaluminate was the dominant phase when calcined above 1100 degreesC. Moreover, the UV-Vis-DR result verified that Fe occupied the Oh sites in Fe-hexaaluminate structure. With the increase of Fe content (xless than or equal to3), the activity of hexaaluminate for methane combustion was raised. The most active catalyst was BaFe3Al9O19-delta, the light-off temperature of which was 515 degreesC. Compared with BaFeAl11O19-delta, the high-temperature activity of Ba0.5La0.5FeAl11O19-delta increased greatly, no obvious promotion for methane ignition activity was observed. The reactant atmosphere had impact on methane ignition activity, but slight influence on high-temperature activity due to the transport limitation. Stability experiment was carried out at 800 degreesC for 100 h, and no deactivation was detected. |
