VEGETABLE OIL AND DISTILLED FATTY ACID PROCESSING CATALYST AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2008 - IPC B01J37/02 B01J35/04 B01J32/00 B01J23/44 

FIELD: hydrogenation-dehydrogenation catalysts.

SUBSTANCE: invention relates to catalysts exhibiting activity in hydrogenation of vegetable oils and fats and suitable for use in food processing industry, perfumery, petrochemical and petroleum processing industries. Invention describes a method for preparing granulated catalysts intended for liquid-phase hydrogenation of vegetable oils and distilled fatty acids and representing metallic palladium deposited in amount 0.5-2.0 wt % on carbon carrier, fraction 0.5-6.0 mm, having specific surface area 100-450 m²/g and pore volume 0.2-0.6 cm³/g. Hydrogenation process is conducted on fixed catalyst bed at 140-210°C, hydrogen pressure 2 to 12 atm and consumption or raw material 100 to 1500 g/h per 1 kg catalyst.

EFFECT: increased hydrogenation rate in production of technical sorts of solidified fat and increased stability of catalysts.
