It has been shown that the phase composition of the support has a significant effect on the activity of supported Pd/WZ catalysts based on it. Upon transition from a set of θ- and δ-Al<sub>2</sub>O<sub>3</sub> phases to the θ- and α-Al<sub>2</sub>O<sub>3</sub> phase composition has led to an increase in the activity of the catalysts, as evidenced by a shift of 10–30°C in the temperature dependences of the heptane conversion to lower temperatures. The appearance of the α-Al<sub>2</sub>O<sub>3</sub> phase is accompanied by a decrease in the specific surface area of the catalysts, which leads to an increase in the density of acid sites and, as a consequence, a change in activity. The Pd/WZ catalysts supported on S aluminas are characterized by a higher acidity (3.7–6.3 μmol/m<sup>2</sup>) as compared to the samples supported on E aluminas (2.8–3.6 µmol/m<sup>2</sup>). The high acidity of the Pd/WZ/S catalysts intensifies the heptane cracking side reactions to form gaseous C<sub>1</sub>–C<sub>4</sub> hydrocarbons.
