Abstract
A process for the heterogeneously catalyzed gas-phase partial oxidation of an organic compound over a fixed catalyst bed present in a fixed-bed reactor having a plurality of catalyst tubes, in which the reduction of the quality of the catalyst load with increasing duration of operation is restored by a partial catalyst change, is described.

A process for the heterogeneously catalyzed gas-phase partial oxidation of at least one organic compound with molecular oxygen over a fixed catalyst bed present in a fixed-bed reactor containing a plurality of catalyst tubes, in which there is an increasing reduction of the quality of the catalyst load with increasing duration of operation from a specific operating time, wherein, in order to recover the quality of the catalyst load, only a portion of spent catalyst load, instead of the entire spent catalyst load, is removed from the fixed-bed reactor containing a plurality of catalyst tubes and is replaced by a fresh catalyst load.
