Abstract: The effect of the reduction period in hydrogen of Pd/Sibunit and Pd–M/Sibunit (M: Ga, Zn, Ag) catalyst, as well as the nature of palladium and zinc precursors on properties of samples in the of liquid-phase hydrogenation reaction of acetylene into ethylene was investigated. It was found that the introduction of the second metal (Ga, Zn, and Ag) into the Pd catalyst prevented sintering of the active component during reductive thermal treatment resulting in the reduction period does not affect the activity and selectivity of the modified catalysts, unlike an unmodified Pd/Sibunit sample. For the Pd–Zn/Sibunit sample, it was demonstrated that modification with zinc led to a change in the nature of catalytic active sites and an increase in their number, regardless the nature of metal precursors; herewith, the Pd–Zn/Sibunit system synthesized from solutions of palladium nitrate and zinc nitrate is distinguished by a higher activity and selectivity.
