Abstract: The effect of zirconia precursor in Pt-containing WO3/ZrO2 catalysts on isomerization of n-heptane was studied. Samples synthesized with zirconium sulfate as a ZrO2 precursor were shown to be more active in comparison with those synthesized from zirconium oxychloride. The enhanced activity of samples synthesized from zirconium sulfate is caused by a residual (1–1.3 wt. %) content of sulfate ions in the catalysts, which increases the catalyst acidity; as a result, the samples synthesized with zirconium oxychloride as a ZrO2 precursor are more selective. Characteristics of WO3/ZrO2 catalysts containing Pt or Pd as a metallic component were compared in n-heptane isomerization. The use of Pd as a hydrogenating component of tungstated zirconia catalysts was shown to improve the performance of n-heptane isomerization in comparison with the catalysts where the metallic component was represented by Pt.
