Abstract
Samples of the powdered catalysts Pd/C and Pd/Ox, which were synthesized by depositing 0.5 and 1.0 wt.% Pd on carbon materials (Sibunit 159k, thermal black Т-900, Vulcan XC-72R) and oxide supports (Ox: γ-Al2O3, Cr2O3, Ga2O3, TiO2, Ta2O5 and V2O5, and kieselguhr FW-70), were studied. Their catalytic properties were investigated in the partial hydrogenation of sunflower oil. Comparative testing of the catalysts was performed in the kinetic mode using a static Parr reactor to estimate their activity and trans-isomerization selectivity. The effect of the average size of supported palladium particles (dCO) on the indicated characteristics in a wide range of dCO values was discussed.
