Zusammenfassung:FIELD: hydrogenation-dehydrogenation catalysts. ^ SUBSTANCE: invention relates to production of catalyst for selective hydrogenation of diene hydrocarbons, which can be used for hydrofining of liquid pyrolysis products. Catalyst is an active palladium component deposited in amount 0.01-1.0% on inorganic porous support. The latter has mesopores having diameters no less than 4 nm and no bigger than 20 nm, constituting 80 to 98% of the total pore volume in the catalyst, and is characterized by specific surface value 10 to 40 m2/g and total pore volume 0.1 to 0.2 cc/g. ^ EFFECT: increased activity and selectivity of diene hydrogenation process. ^ 2 cl, 1 tbl, 11 ex
