Part of Springer Nature. A mathematical model is developed to assess the effect of cascading sets of enzyme reactors and physical separators, when compared with the classical unit operation approach, in terms of total time required to effect reaction and separation for a given overall conversion. A dynamic model of batch enzymatic reactive distillation was developed based on equilibrium stage approach and served as simulation tool for sensitivity analysis of the process. This work presents a feasibility study for an enzymatic reaction in a continuously operated reactive distillation column and describes the reaction kinetics by means of the MichaelisMenten double-substrate kinetic model in combination with the Arrhenius model.
