In this work, γ-Al2O3 supported Pt catalysts (Pt/γ-Al2O3) were prepared by adsorption method. The characteristics of the Pt catalysts were evaluated using X-ray diffraction, nitrogen adsorption, CO chemisorption analysis and transmission electron microscopy. The influence of temperature, partial pressure of hydrogen, concentration of catalyst, and agitation speed on the formation of trans isomers during hydrogenation of sunflower oil was investigated. The results indicated that the prepared Pt catalysts exhibit excellent activity and selectivity and produce solid fat that meet the international standards, owing to the considerable decrease in the percentage of trans isomers. Low concentration of platinum (0.2%) and the possibility to reuse it opens up new perspectives for its industrial application in the process of partial hydrogenation of vegetable oils.
