Results of studying the Pd/C and Pd/O powder catalysts synthesized by the deposition of 0.5 and 1.0 wt % Pd on carbon materials (Sibunit 159k, thermal carbon black T-900, Vulcan XC - 72R) and oxide supports (Ox: γ-Al 2 O 3 , Cr 2 O 3 , Ga 2 O 3 , TiO 2 , Ta 2 O 5 , and V 2 O 5 , diatomaceous earth FW-70) and their catalytic properties in the partial hydrogenation of sunflower oil were described. Using a Parr fixed-bed reactor, comparative tests of the catalysts in the kinetic mode conducted to determine their activity (SCA, V 0 ) and trans -isomerization selectivity parameters ( S tr ). The effect of the average particle size of supported palladium ( d CO ) on these parameters in a wide range of d CO values was discussed.
