Abstract: Various embodiments of the invention herein described generally relate to novel processes for the production of aromatic acids by fixed bed catalytic oxidation of aromatic compounds carrying at least one oxidizable substituent group attached directly to the carbon atom of the corresponding aromatic nucleus. In an embodiment, a novel oxidation process of the present invention comprises the steps of: a) catalytically oxidizing, with an oxidation catalyst, a liquid phase aromatic acid precursor in the presence of a gaseous oxygen source; b) separating a finished product; c) purging the solvent and the oxidation catalyst; d) optionally recycling at least a portion of the solvent into the oxidation reactor; e) recovering at least a portion of the oxidation catalyst; f) recharging the at least a portion of the oxidation catalyst over a solid recharging catalyst bed; and (g) feeding a reactivated oxidation catalyst to the oxidation reactor.
