EVALUATION OF THE SELECTIVITY OF VEGETABLE OIL HYDROGENATION IN REAL REACTORS

The model of consequent first order reactions was used for the calcula tion of linoleic and linolenic selectivity with respect to fatty acids . The values of reaction rate constants were attained through the eval uation of experimental data of concentration of all the fatty acids wi th 18 C atoms by means of optimizing calculation. Calculated selectivi ty data are discussed in relation to three ways of input of the inlet data: A) From two experimental points at the beginning and end of reac tion at the iodine number higher than 80; B) from 4-6 experimental poi nts in the initial stage of reaction up to the iodine number higher th an 80; C) from 6-8 experimental points for the course of hydrogenation up to the iodine number values 30-60. The reaction rate is discussed simultaneously. The calculated selectivity values and reaction rates a re further discussed in relation to the reaction induction period, rea ction conditions and type of used oil.
