The kinetic model of the process of a-pinene hydrogenation was suggested which takes into account the behavior of chemical reactions both in liquid phase and in gaseous phase. The two-phase mathematical model of the process in a tubular reactor was developed that considers a reaction mixture mole numbers due to hydrogen drawing on a hydrogenation reaction and also due to a phase transfers under the evaporation or the condensation of the components. The thermodynamic approach was proposed for a determination of the phase transfer velocity. The numerical analysis of the process in a tubular reactor was carried out under cocurrent or countercurrent flows of the reaction mixture and cooling water. The preference of the cocurrent reactor using was shown.
Key words: a-pinene hydrogenation, tubular reactor, chemical reactions, mathematical model.
