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 temperat...
In a process for the oxidation of ortho-xylene by contact of ortho-xylene and oxidizing gas with fluidized solid catalyst at oxidation reaction conditions, the improvement which comprises carrying out the reactive contact in a first contact zone at a temperature in the range of 300°C. to 500°C. until 60-95% of the ortho-xylene is reacted, passing the reaction gas mixture containing unreacted ortho-xylene ad catalyst to second contact zone which has a greater volume than said first contact zone and which is maintained at a temperature at least 50°C. lower...
