The general context of this work is the regeneration of the catalyst based on vanadium pent oxide. The purpose of regeneration is the reuse of the catalyst after a lifetime that does not exceed ten years. To accomplish this task, we proceeded according to three different methods of regeneration; thermal, chemical and chemical coupled with electromagnetic treatment. Catalytic tests were conducted in a micro reactor to decide on the most efficient regeneration method. The experimental results of the catalytic tests of the regenerated catalyst by the chemical and thermal method have showed a delay in triggering the conversion compared to the fresh catalyst. In order to overcome this phenomenon, we have tried the method of chemical regeneration coupled with an electromagnetic treatment given the importance of the impregnation stage in the increase of the active phase and the primordial role of the electromagnetic waves in the creation of pores and the improvement of the dispersion of the active phase. This method has recovered more than 80% of spent catalyst activity.
