Resumen:
The use of structured zeolitic materials for environmental applications has increased considerably. The advantage of the in-situ synthesis [1] to structure zeolites is that a stronger adhesion to the support can be achieved. However, the accessibility to the active sites within the zeolite framework is also important. The secondary synthesis can help in obtaining preferential orientations which favor the catalytic performance [2]. For some applications, metallic substrates are preferred due to their higher mechanical resistance and thermal conductivity and the possibility of allow higher cell densities with low pressure drop [3]. For these reasons we have produced and characterized a ZSM5 structured catalysts in the form of a coatings onto FeCrAl alloy supports. The catalytic performance was evaluated in the selective reduction of NOx with methane by exchanging In as active material. For some applications, metallic substrates are preferred due to their higher mechanical resistance and thermal conductivity and the possibility of allow higher cell densities with low pressure drop [3]. For these reasons we have produced and characterized a ZSM5 structured catalysts in the form of a coatings onto FeCrAl alloy supports.
