Abstract
Optimal feed temperature was determined for a non-isothermal fixed-bed reactor performing hydrogen
peroxide decomposition by immobilized Terminox Ultra catalase. This feed temperature was
obtained by maximizing the average substrate conversion under constant feed flow rate and temperature
constraints. In calculations, convection-diffusion-reaction immobilized enzyme fixed-bed reactor
described by a set of partial differential equations was taken into account. It was based on kinetic, hydrodynamic
and mass transfer parameters previously obtained in the process of H2O2 decomposition.
The simulation showed the optimal feed temperature to be strongly dependent on hydrogen peroxide
concentration, feed flow rate and diffusional resistances expressed by biocatalyst effectiveness factor.
