A process for regeneration of a catalyst that comprises at least one EUO-structural-type zeolite in acid form and at least one hydro-dehydrogenating metal, used in a process for isomerization of a hydrocarbon feedstock that comprises aromatic compounds with eight carbon atoms, comprising at least a) a stage for eliminating a majority of the coke, deposited on said catalyst, by combustion in the presence of a gas that contains oxygen at a temperature that is less than or equal to 600° C., and b) a stage for oxychlorination of the product that is obtained from stage a), carried out between 200 and 550° C. in the presence of at least one gas mixture that contains at least oxygen, water and chlorine and/or at least one chlorinated compound, is described. |
