中文摘要：

以FeCrAl合金薄片为基体，Al2 O3为过渡载体，Ce1-xNixO2（x=0．1-3）、CeO2和NiO为活性组分，制备了Ce1-xNixO2／Al2O3／FeCrAl、CeO2／Al2O3／FeCrAl和NiO／Al2O3／FeCrAl金属基整体式催化剂，在固定床微型反应器中评价了催化剂的甲烷催化燃烧性能，用SEM、XRD、TPR等方法对催化剂的物相、表面形貌和氧化还原性进行了表征．结果表明，Ce1-xNixO2在催化剂表面的分散性比CeO2和NiO要好；Ce1-xNixO2／Al2O3／FeCrAl（x=0．1-0．3）催化剂具有好的催化活性和高温稳定性，CeO2／Al2O3／FeCrAl和NiO／Al2O3，／FeCrAl催化剂有好的初活性但高温稳定性较差；活性组分与Al2O3和FeCrAl金属基体之间存在较强的相互作用．

英文摘要：

A series of Ce1-xNix O2/Al2O3/FeCrAl （ x = 0.1-0.3）, CeO2/Al2 O3/FeCrAl and NiO/Al2O3/FeCrAI monolith catalysts were prepared using the FeCrAl alloy foils as support, Al2O3 as washcoat layer and Ce1-x NixO2 solid solution, CeO2and NiO as active component. The catalytic activity of the catalysts for the combustion of methane was evaluated in a conventional quartz flow reactor. The structure of the catalysts was characterized using XRD, SEM and H2-TPR. The results indicate that Ce1-xNixO2 solid solution was well dispersed on the surface of the catalyst support. The Ce1-xNi, O2/Al2O3/FeCrAl catalysts had a good catalytic activity and thermal stability for the combustion of methane. The CeO2Al2O3/FeCrAl and NiO/Al2O3/FeCrAl catalyst had a well initial catalytic activity, but the thermal stability for the combustion of methane was not good. There were a strong interaction among the Cet1-x,Nix O2 solid solutions and the Al203 washeoat and the FeCrAl alloy foils support.
