FIELD: chemistry.

SUBSTANCE: invention relates to catalysts, particularly designed for hydrogenating triglycerides of plant oil and fat and can be used in food, perfumery, petrochemical and oil-refining industry. The invention describes a catalyst for hydrogenating unsaturated hydrocarbons, preferably plant oil and fat, which contains catalytically active palladium in amount of 0.1-5.0 wt % deposited on the surface of a solid support in form of active aluminium oxide with average mesopore size between 20 and 500 nm, on the surface of which there is a 3-30 nm layer of pyrocarbon. The invention describes a method of preparing the catalyst by depositing 0.1-5.0 wt % catalytically active palladium onto the surface of an active aluminium oxide support with average mesopore size between 20 and 500 nm, on whose surface there is a 3-30 nm layer of pyrocarbon, followed by drying, decomposition and reduction of palladium. Described also is a method of hydrogenating unsaturated hydrocarbons using the said catalyst.

EFFECT: high efficiency at given quality of hydrogenated fat (content of trans-isomers and iodine number).
