Resumen:
A variety of metal cation-containing zeolites have been studied as HC-SCR catalysts. However, the low hydrothermal stability of these zeolites have impaired their practical application. In this vein, the combination of Co-zeolites with a nobel metal (Pt or Pd) has been proposed and these bimetallic catalysts improve the zeolite water resistance; however, some deactivation proceeds after 50 h on stream [1-3]. On the other hand, it is well known that rare earth incorporation to Y zeolites increases its stability [4]. In this work, we have studied the effect of lanthanum addition to the mordenite system in order to improve the hydrothermal stability of CoHMordenite for the SCR of NOx with methane.
