Abstract

AbstractA model involving competitive adsorption of reactants for hydrogenation of fatty acids was developed and analyzed. The model was established based on data obtained from catalytic transfer hydrogenation of peanut, corn, and soybean oils and soybean lecithin with aqueous sodium formate solution as the hydrogen donor and palladium on carbon as the catalyst. The predicted values based on the model agreed well with the experimental data as indicated by the r2 and F test values. The rate of formate consumption, which decreased with time and the initial amount of formic acid versus the iodine value, was explained with regards to the mathematical model developed. Adsorption of reactants on the catalyst surface followed by a chemical reaction including participation of the fatty acid, formate and water were considered in this model.
