Abstract: The process,electrochemical reduction of nitrobenzene to produce p-amino-phenol in a packed bed electrochemical reactor, is investigated. The reactor is desiged with the aid of the reactor model established in the literature [7,8] of the study. Applying this model, the authors calculate the model of the reduction of nitrobenzene for p-aminophenol process and compare with the experiments. The experimental results show that this process can be operated at acurrent density i≥2000A/m2, selectivity β≥80.0%, and current effenct ηi75.0%. This study provides a very important basis for the industrialization of the studied process.
