PP-I-23The equation of the reaction rate (W) dependence on the concentrations of the reactionmixture components (C i ) and some of elementary constants (k i ) was proposed on the base ofthermodynamic estimations (advanced model on Fig. 2). The optimal kinetic model of theprocess was defined by solving the inverse kinetic problem. The difference between themodel and experimental reaction rates was minimized. The activation energies and formalreaction orders on reaction components were also determined.ConclusionsWCH3OH, mol/g*s876543210simple modeladvanced modelexperiment3 3.5 4 4.5 5C CH3OH , vol.%Figure 2.
