1. catalytic wet oxidation process comprises:

  • The aqueous mixture that comprises at least a pending undesirable component is provided;

    Under the temperature that raises and superatmospheric pressure this aqueous mixture contact with oxygenant with catalyzer, with this at least a undesirable component of processing, and formation is through the aqueous mixture of oxidation;

    By regulating this through the pH of the aqueous mixture of oxidation level, this catalyzer of precipitation at least a portion is to form precipitated catalyst;

    WithWith this precipitated catalyst recirculation of at least a portion to contact with this aqueous mixture.
