FIELD: chemistry.
SUBSTANCE: invention relates to the field of chemical technology for the production of catalysts, in particular, catalysts for selective hydrogenation of propane-propylene fraction (PPF). A method for preparing a catalyst for selective hydrogenation of PPF is proposed, including impregnation of an aluminum oxide-based carrier with solutions of metal salts, namely, palladium and silver salts, followed by washing, drying and calcination.
EFFECT: creation of a method for obtaining a catalyst for selective hydrogenation of PPF, which has good characteristics, in particular, has high selectivity and provides for almost complete conversion of methylacetylene and propadiene with minimizing the side reaction of hydrogenation of propylene into propane.
