Dynamic behaviour of electrochemical reactors for a step change in inlet concentration under potentiostatic control according to the dispersion model

摘要

The dynamic modelling of electrochemical reactors under potentiostatic control is performed according to the dispersion model. The response of the system in concentration and current is discussed for a step change in the inlet concentration in terms of the Peclet number. The stirred tank and plug flow behaviours are analyzed as limiting cases of the dispersion model.
