Abstract
Platinated W/Zr mixed oxides supported on mesoporous silica with various amounts of Si/Zr, namely Pt-WO3/ZrO2(x)-HMS, were prepared and studied for n-heptane isomerization reaction at 200–350°C. 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.
