METHOD OF HYDROGENATING PLANT OIL AND DISTILLED FATTY ACIDS Russian patent published in 2012 - IPC C11C3/12 B01J23/44 B01J35/04 B01J32/00 

FIELD: chemistry.

SUBSTANCE: hydrogenation is carried out on a fixed-bed catalyst which is in form of crystallites of catalytically active palladium, deposited on the surface of carbon material, the carbon material being mesoporous graphite-like material with granule size 0.5-6.0 mm, preferably 3.0-6.0 mm, with specific surface area 100-450 m²/g, mean mesopore size from 40 to 400Ǻ, total pore volume 0.2-0.6 cm³/g and fraction of mesopores in total pore volume not less than 0.6, in which palladium crystallites inside the granules of the carbon material are distributed such that distribution maxima of the active component lie at a distance from the outer surface of the granules which is 1-30% of the radius of the granules, with content of deposited palladium from 0.5 to 2.0 wt %.

EFFECT: high rate of hydrogenating material when producing industrial grades of hydrogenated fats and high stability.
