摘要：
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: gamma-Al2O3, Cr2O3, Ga2O3, TiO2, Ta2O5, and V2O5, 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.
