METHOD FOR HYDROGENATION OF VEGETABLE OIL AND DISTILLED FATTY ACID Russian patent published in 2008 - IPC C11C3/12 B01J23/44 B01J35/04 B01J32/00 

FIELD: oil and fat industry and technology.

SUBSTANCE: invention relates to an improved method for hydrogenation of vegetable oils and distilled fatty acids. Method involves the hydrogenation reaction that is carried out on a catalyst stationary layer representing crystallites of active palladium applied on surface of carbonic material wherein mesoporous graphite-like material is used as carbonic material with granules size 0.5-6.0 mm but preferably 3.0-6.0 mm, specific surface 100-450 m²/g, average size of mesopores in the range from 40 to 400 Å, total volume of pores 0.2-0.6 cm³/g and part of mesopores in the total volume of pores 0.6, not less. Palladium crystallites in volume of carbonic material are distributed by so manner that the distribution maximum values of active component are in distance from external granule surface corresponding to 1-30% of its radius and in the content of applied palladium in the range from 0.5 to 2.0 wt.-%. Invention provides the high hydrogenation rate of raw in production of technical sorts of hydrogenated fats and high stability of product.

EFFECT: improved method of hydrogenation.
