Abstract: Nonequilibrium model for steady state simulation of catalytic distillation is presented. Mathematical model takes into account
both mass and heat transfers across the gas liquid interface and through the liquid-solid (catalyst) interface. Equations
describing the mentioned phenomena are based on the effective diffusivity approach. The resulting system of nonlinear algebraic
equations was implemented in the FORTRAN programming language and solved by the BUNLSI (Ferraris & Tronconi, 1986) solver.
The described model was verified using the experimental data obtained from a continuous distillation column equipped with
catalytic packing. As an experimental model system, synthesis of propyl propionate from propan-1-ol and propionic acid was
chosen. Comparison of experimental and simulation data is presented, and appropriateness of the developed model for other
types of catalytic distillation processes is discussed.
Keywords: nonequilibrium model - catalytic distillation - reactive distillation - propyl propionate synthesis
