Abstract:
Nanosized palladium catalysts supported on mesoporous carbon Sibunit were developed for hydroprocessing of natural oil feedstocks to produce harmless nickel-free margarine and confectionery fat with high organoleptic quality. The effects of supports chemical pretreatment, catalyst particle size, Pd loading and the type of vegetable oil were studied. The laboratory as well as pilot-scale behavior of Pd catalysts for the oil hydrogenation in comparison with Ni counterparts was evaluated. Sunflower oil hydrogenation was studied in a laboratory batch reactor over Pd/C (Sibunit) at 413 K and hydrogen pressure of 9 bar using catalyst samples with different palladium loading and support grain size. 0.1 wt.% Pd/C showed the same activity during 21 repeated cycles of sunflower oil hydrogenation with catalyst/oil weight ratio = 1/100-1/1000 producing as much as 1797.5 kg hydrogenating oil per 1 g Pd without being deactivated. The same samples 0.1 wt.% and 1 wt.% Pd/C were tested in a pilot set up with the catalyst/oil weight ratio = 1/100-1/1000 displaying the similar activity as commercial Ni catalysts.
