The effect of reduction temperature of a Pt/WO3/ZrO2 catalyst (200–500 °С) on indicators of n-heptane isomerisation was studied. It was found that the maximum yield of the desired reaction products that are high-octane di- and trimethyl-substituted (DTMS) n-heptane isomers was reached (27–31 mass %) in the region of the 250–300 °С. A rise in reduction temperature of the catalyst to 400–500 °С leads to an increase in the number of Lewis acid sites in 1.6–1.7 due to partial reduction of tungsten on the WO3/ZrO2 surface, which contributes to an increase in the catalyst activity; herewith, selectivity by the target products decreases due to enhancing side reactions of n-heptane cracking.
