✦ Synopsis


A mathematical model was developed for a catalytic, batch-wise operating basket reactor used for liquid-phase systems. This kind of reactor is frequently used to study the reaction kinetics and diffusion effects in porous catalyst particles. The model comprises dynamic mass balances for the catalyst particles and the turbulent liquid phase surrounding the particles. Simultaneous reaction and diffusion in particles is handled by the model, which was successfully applied to describe the kinetic and mass transfer effects in a complex organic reaction system, which is relevant for catalytic recovery of anthraquinones. The model predicted the reactor performance for different catalyst particle diameters, which is relevant for a successful process scale up.
