FIELD: chemistry.
SUBSTANCE: invention relates to catalysts designed for hydrogenating triglycerides of plant oil and fat and can be used in food, perfumery, petrochemical and oil-refining industry. Described is a catalyst which contains 0.1-2.0 wt % catalytically active palladium which is deposited on the surface of carbonaceous material. The specific surface area of the catalytically active palladium on the surface of the carbonaceous material is equal to 5-20 m2/g. Over 90% of the palladium is in the surface layer of the carbonaceous material whose thickness is not greater than 25% of the diametre of particles of the carbonaceous material which has particle size distribution of 50-250 mcm.
EFFECT: high activity (efficiency) and reduced formation of trans-isomers when producing hydrogenated fat for food purposes.
