FIELD: chemistry.
SUBSTANCE: invention relates to catalysts, particularly, to those intended for hydration of vegetable oil and fat and may be used in food, chemical and petrochemical industries. Proposed method comprises preparing granulated catalysts for liquid-phase hydration of vegetable oils and distilled fat acids by hydrogen that represent metallic palladium applied in amount of 0.5-2.0 wt % on carbon carrier of 0.5-6.0 mm-fraction with specific surface of 100-450 m2/g and volume of pores of 0.2-0.6 cm3/g. Hydration is conducted on catalyst stationary bed at 140-210°C, hydrogen pressure of 2 to 12 atm and raw stock consumption of 100 to 1500 g/(kgkt·h).
EFFECT: high hydration rate and stability of technical brands.
