Abstract

The structure and physicochemical properties of palladium catalysts used in liquid-phase hydrogenation processes were studied with the use of adsorption, calorimetric, thermogravimetry, and temperature-programmed reduction techniques. The specific surface areas and average sizes and volume of pores of the adsorbents were determined. The palladium on activated carbon catalysts was found to possess a complex porous structure, whereas palladium on combined alumina and coal carrier catalysts is an adsorbent with a nonporous structure. The concentration of the applied metal and the nature of a support have a significant impact on the physicochemical properties of palladium catalysts.
