A simplification of the Horiuti‐Polanyi reaction scheme for the hydrogenation of triacylglycerols taking into account saturation and cis‐trans isomerization of double bonds and neglecting their positional isomerization is presented. From the comparison of experimental and calculated kinetic runs, the rate constants of individual reaction steps are obtained and the effects of hydrogen flow, hydrogen dispersion, oil unsaturation and catalyst quality on the rate constants are examined. Criteria for comprehensive characterization of the processes occurring in the course of hydrogenation, i.e., saturation and isomerization indices, are proposed.
