Abstract

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-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, V₀) 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.

摘要

研究通过在碳材料（Sibunit 159k、热炭黑 T-900、Vulcan XC - 72R）和氧化物载体（Ox：γ）上沉积 0.5 和 1.0 wt% Pd 合成的 Pd/C 和 Pd/O 粉末催化剂的结果描述了Al ₂ O ₃、Cr ₂ O ₃、Ga ₂ O ₃、TiO ₂、Ta ₂ O ₅和V ₂ O ₅、硅藻土FW-70）及其在葵花籽油部分加氢中的催化性能。使用帕尔固定床反应器，对催化剂进行动力学模式对比测试，以确定其活性（SCA，V ₀）和反式异构化选择性参数（St _tr）。讨论了负载钯的平均粒径 ( _dCO )在较宽的dCO_{值范围内对这些参数的影响。}
