Treatment of aniline by catalytic wet air oxidation: Comparative study over CuO/CeO_2 and NiO/Al_2O_3

摘要

The treatment of aniline by catalytic wet air oxidation (CWAO) was studied in a bubble reactor. The experiments were performed to investigate the effects of catalyst loading, temperature, reaction time, air flow rate, and pressure on aniline removal. The catalytic effects of the prepared nanostructured catalysts, CuO/CeO_2 (10% wt) and NiO/Al_2O_3 (10% wt), on the CWAO treatment efficiency were also examined and compared. The prepared catalysts seem to be active having an aniline removal of 45.7% with CuO/CeO_2 and 41.9% with NiO/Al_2O_3. The amount of N_2 formed was approximately the same for both of the catalysts.
