Abstract: An influence of the preparation method and rhenium oxide content in the PdO-Re2O7/SO4 2-/ZrO2 system was studied. Optimal method of catalyst preparation is impregnation of support by solution of palladium precursor and then by solution of rhenium precursor. The maximum yield of propylene (49 wt. %) is achieved on the PdO-Re2O7/SO4 2-/ZrO2 catalyst with 1.87 wt. % Re2O7 at the temperature of 80˚C and weight hourly space velocity of 0.5 h-1
