A criterion is developed for the optimum operation of an isothermal fixed bed reactor using a deactivating immobilised enzyme catalyst. The chemical reaction is assumed to follow a Michaelis-Menten type kinetics, and the deactivation is assumed to depend only upon the temperature of operation. An explicit equation for dT/dt is derived from the criterion which makes it possible to calculate the optimum reactor temperature as a function of time in a straightforward manner for a given initial temperature by standard numerical integration techniques. It turns out that the optimum temperature policy results in a varying conversion at the reactor outlet. A numerical example is presented which indicates that such a policy is better than both a constant temperature policy and a constant conversion policy. The techniques developed here can also be used for a gas-solid catalytic reactor involving Langmuir-Hinshelwood kinetics with concentration independent deactivation. |
