Abstract

The feasability of paracetamol catalytic wet air oxidation (CWAO) on activated carbons (ACs), as well as the stability of ACs were studied. Three ACs from different source materials (L27, S23 and C1) were used. The adsorption equilibrium on fresh particles (sieved to 800-1000 μm) was reached after 2 hours under nitrogen before oxidation reactions were started, revealing that both adsorption capacity and catalytic performance of fresh S23 and C-1 were higher than those of fresh L27. In all cases, the degradation and mineralization of paracetamol decrease when the AC is recycled. Although L27 was less efficient in the first cycle, the best results were obtained for it after five CWAO cycles, which can be explained by its higher mesoporous/microporous ratio.
