This paper describes the modeling of a novel perforated bipole electrochemical reactor with trickle-bed cathodes employed in the electrosynthesis of alkaline peroxide solutions. The model engages an electronic analogue of the 3D electrode/bipoles to solve the coupled material, energy and voltage (charge) balances that estimate the potential, current density, composition, pressure and temperature profiles through the reactor. The predictions of this model are compared to the performance of a bench scale experimental reactor operating at superficial current densities up to 5 kA m(-2). With eddy diffusion through the diaphragm as the single adjustable parameter the model shows good agreement with peroxide current efficiency but underestimates the electrochemical specific energy consumption by about 2 kWh/kg H2O2 at 5 kAm(-2).
