FIELD: petrochemical processes.
SUBSTANCE: hydrocarbon fractions are brought into contact, in presence of hydrogen-containing gas, with catalyst containing palladium on porous carrier, which contains mesopores with diameters no less than 4 nm and no large than 20 nm constituting 80 to 98% of the total volume of pore within a range of 4 to 20 nm.
EFFECT: deepened hydrogenation process due to increased catalyst activity regarding diolefins and selectivity regarding aromatic hydrocarbons.
