AB - The semi-batch wet oxidation of p-coumaric acid, a biorecalcitrant polyphenolic compound typically found in olive processing and wine-distillery wastewaters, using a CuO.ZnO-Al2O3 catalyst in slurry form at temperatures from 373 K to 403 K, oxygen partial pressures from 2.3 to 32.3 bar, catalyst concentrations from 0.088 to 4.4 g I-1 and particle size from 38-250 μm, has been investigated. The catalyst was found to be capable of increasing the rate of p-coumaric acid oxidation by as much as 20 times that of the uncatalysed reaction, at 403 K. The rate of p-coumaric acid oxidation was found to be first order with respect to its concentration and proportional to oxygen partial pressure to the power of 0.65 over the range of operating conditions where oxygen partial pressure exerts a significant effect (2.3 to 17.3 bar). With the particle sizes used, there were no intraparticle diffusional limitations.
