CATALYST FOR HYDROGENATING PLANT OIL AND FATS, PREPARATION METHOD THEREOF AND HYDROGENATION METHOD Russian patent published in 2011 - IPC B01J23/44 B01J23/46 B01J21/18 B01J37/03 B01J37/16 C11C3/12 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to catalysts, particularly used in hydrogenating plant oil and unsaturated fats and can be used in food, perfumery, pharmaceutical, petrochemical and oil-refining industry. Described is a catalyst which contains palladium in amount of 0.1-5.0 wt % and ruthenium in ratio Pd:Ru=1-100 in form of bimetallic particles with size 1-6 nm deposited on a carbon support. Described is a method of preparing the catalyst, involving preliminary combined hydrolysis of palladium (II) and ruthenium (III) chlorides at pH 5-10 and then bringing the precursor into contact with the carbon support and liquid-phase reduction. Described also is a method of hydrogenating triglycerides of plant oil and fats at temperature 80-200°C and pressure 2-15 atm using the catalyst described above.

EFFECT: high efficiency of the method of preparing the catalyst.
