Platinated W/Zr mixed oxides supported on mesoporous silica with various amounts of Si/Zr, namely PtWO₃/ZrO₂(x)-HMS, were prepared and studied for n-heptane isomerization reaction at 200-350℃. The various methods such as XRD, XRF, FT-IR, UV-vis DRS, NH₃-TPD, H₂ chemisorption, nitrogen adsorption-desorption, Py-IR, SEM and TGA techniques were used for characterization of these materials. Kinetics of n-heptane isomerization was also investigated under various hydrogen. n-Heptane pressures and the influence of reaction conditions on catalytic performance were studied. The ideal catalytic performance was observed on HMS with 0.6%Pt/12%WO₃/ZrO₂ and Si/Zr=10.
