Abstract
The invention concerns a rejuvenation process for a solid catalyst for the alkylation of at least one isoparaffin by at least one olefin. The process is characterised in that the catalyst is rejuvenated in the reaction zone by circulating an isoparaffin-rich liquid fraction over the bed, said fraction originating from a zone for separating the reaction effluent extracted from the reaction zone.
