Abstract
The present invention relates to the oxidation of organic compounds in a non-uniform fluidized solid catalyst reaction system characterized in that a temperature profile is maintained in the reaction system such that a predominance of the oxidation occurs in a higher temperature zone, unreacted organic compound is adsorbed on the catalyst surface in a lower temperature zone, direct back-circulation of catalyst is restricted between zones and catalyst containing adsorbed organic compound is circulated from the lower temperature zone to the higher temperature zone.
