Resumen:
The present contribution reports an experimental study of
the oxidation of phenol aqueous solutions over a CuO/γ-Al2O3
catalyst carried out in a trickle bed reactor. Steady-state as well as
periodic on-off experiments were performed. In the range of operating
conditions studied, it was observed that liquid flow modulation has a
mild effect on phenol conversion but it does affect product
distribution, favoring the mineralization process. When the liquid flow
is halted, the intermediate products remain inside the catalyst and are
further oxidized to final products. The residence time of the
intermediates and the average oxygen concentrations inside the catalytic
pellet during liquid flow modulation are higher than those attained in
steady-state operation.
