Abstract:
Hydrogenation of vegetable oils was first discovered in the beginning of the 20th century and quickly became a major processing step in the fats and oils industry. Soybean oil has been partially hydrogenated in the presence of a synthesized nickel catalyst, in an industrial reactor, under the standard industrial working conditions. The presented model in this study is established, which could be useful for the characterization of the
hydrogenation and isomerization reactions of poly-unsaturated acids. Iteration procedure, incorporating numerical simulation in each step is used to calculate rate constants of the proposed model from the comparison of the experimental and calculated kinetic runs. By the simultaneous treatment of the kinetic runs for the fatty acids composition and transisomer content, the 6 rate constants of individual hydrogenation and isomerization reaction steps and obtained.
