A reaction zone is provided comprising a plurality of oxygen clean up zones and a plurality of oxidation zones. A first stream is introduced to oxidation clean up zones comprising liquid cyclohexane, and optionally a cyclohexane oxidation catalyst. In addition, an oxygen containing gas is introduced into the oxidation zones. Next, the first stream is passed downwardly from the oxygen clean up zones to the oxidation zones, while cross-currently passing the oxygen containing gas upwardly from the oxidation zones to the oxygen clean up zones. The oxygen containing gas is introduced directly into the first stream as it travels through the oxidation zones, and the reaction between the first stream and the oxygen containing gas produces a product mixture. Finally, a product mixture is withdrawn from the oxidation zones that comprises CHHP, cyclohexanone and cyclohexanol. |
