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. ^ 4 cl, 1 dwg, 3 tbl, 20 ex |
