Non order structure type HMS was synthesized through a S°I° mechanism. These solids were modified by incorporation of acid (30 wt.% of tungstophosphoric acid) and metallic sites (1% of metal: Pt or Pd), and tested in the hydroisomerization reaction of n-pentane. The catalysts were characterized by X-ray diffraction (XRD), N2 adsorption and desorption, chemisorption of H2, scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). For the catalyst containing Pt, the effect of reaction temperature was investigated in the range of 200-400 °C, the optimal catalytic activity was reached at 350 °C. The Pt catalyst showed higher conversion, iso-pentane yield and catalytic stability than its Pd counterpart. © 2011 Elsevier B.V. All rights reserved.
