Effect of the Impregnation Strategy in the Catalytic Activity of Pd and Mo Supported Catalysts

H. R. Zea and L. M. Carballo

The effect of the impregnation strategy in catalytic activity of Pd and Mo supported on alumina in the oxidative dehydrogenation of propane was studied. Total, metallic superficial areas and total volume of pore behaviour were correlated as a function of the load relationship Mo/Pd and the impregnation strategy. Except for the 3.75 Mo 1.25 PdS catalyst, all the bimetallic catalysts of Pd-Mo present smaller metallic surface area than their corresponding monometallic Pd catalysts. The increment of the specific activities to propene for the bimetallic catalysts in comparison with the monometallic catalysts may indicate modification on the reaction mechanism and the configuration of the surroundings of the active site.
