FIELD: hydrogenation-dehydrogenation catalysts.
SUBSTANCE: catalyst containing catalytically active amounts of Pd and, if needed, Ag on carrier is characterized by that said carrier is a molded product with three-leafed cross section, said leaves being provided with through openings. Catalyst is prepared by impregnating carrier with solution of Pd salts and, if needed, Ag salts, after which salts are reduced by reducing agent, loaded carrier is rinsed, dried, and calcined. If reduction is incomplete, all Pd and Ag oxides available are reduced in hydrogen-containing atmosphere into corresponding metals.
EFFECT: diminished flow resistance and enabled hydrogenation of unsaturated hydrocarbons at high flow rates.
