Resumen:
Different basic materials, such as K-L zeolite, K-Al2O3, K-Mg/Al mixed oxide and MgO,were used as supports of Pt-catalysts for dry reforming of methane (DR) reaction.Platinum acetylacetonate (II) was used as a metallic precursor. The effects of thedistribution of basic strength in the support on the metal-support properties and catalystperformance were evaluated. The density of strong basic sites decreased as follows:MgO>K(Mg-Al) >K-Al2O3>K-L. Pt catalysts supported on materials of high density of strongbasic sites were very adequate for this reforming reaction. The better catalytic behaviour ofPt/MgO catalyst would be related with the good interaction between the metallic phase andthe most basic support. The methane conversion and the H2/CO ratios obtained by DRreaction correlate quite well with the basicity of the different catalysts.
