摘要：

Dealumination of the faujasite support was realised using a hydrothermal treatment at different temperatures (625 - 700 degrees C). Then palladium catalysts were prepared by an ion exchange method. The prepared catalysts exhibited a high and constant activity up to 100% for N2O conversion. This performance was dependent on certain parameters, such as a high Si/Al ratio, the structural properties of the zeolitic support, and the metal function provided by the palladium. In addition, it is considered that the active sites in the reaction, which are suspected to be PdO, are influenced by the acidic properties of the support.
