摘要：Various embodiments of the invention herein described generally relate tonovel processes for the production of aromatic acids by fixed bed catalytic oxidation ofaromatic compounds carrying at least one oxidizable substituent group attached directlyto the carbon atom of the corresponding aromatic nucleus. In an embodiment, a noveloxidation process of the present invention comprises the steps of: a) catalyticallyoxidizing, with an oxidation catalyst, a liquid phase aromatic acid precursor in thepresence of a gaseous oxygen source; b) separating a finished product; c) purging thesolvent and the oxidation catalyst; d) optionally recycling at least a portion of the solventinto 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 catalystbed; and (g) feeding a reactivated oxidation catalyst to the oxidation reactor.
