Abstract

A series of Pd/SBA-15/Al2O3/FeCrAl and Pd/5 wt% Ce1-xZrxO2/SBA-15/Al2O 3/FeCrAl (x=0-1)metal monolithic catalysts were prepared and characterized by various techniques. The catalytic activity and the stability of the catalysts for methane combustion were evaluated. All the catalysts retain the SBA-15 mesoporous structure, with PdO being confined in its channels. The results show that the addition of Ce1-xZrxO2 as promoters can improve the activity and stability of the catalysts. The stabilities of the metal monolithic catalysts are much better than those of Pd/SBA-15 particle catalysts. The catalyst with ZrO2 as promoter exhibits the best activity and stability (T90=395 °C), and the conversion of methane remains constant during the 700 h test. © 2008 Wiley-VCH Verlag GmbH & Co.
