摘要：

Selective catalytic reduction (SCR) of N2O with methane in the presence of steam has been investigated over iron-containing AlPO-5 that is prepared by isomorphous substitution and impregnation, respectively. Characterization results indicate that AlPO-5 zeolite has good capacity to resist steam. FeAlPO-5 has better low-temperature activity and is more stable than Fe/AlPO-5 due to its high population of isolated Fe(III) and oligonuclear Fe(III)(x)O-y. The deactivation of Fe/AlPO-5 is ascribed to agglomeration of Fe2O3 particles under steam condition. (C) 2009 Elsevier B.V. All rights reserved.
