ABSTRACT:
The invention concerns the dismutation of alkylaromatic hydrocarbons, preferably the dismutation of toluene to produce benzene and xylenes, and/or the transalkylation of alkylaromatic hydrocarbons, preferably the transalkylation of toluene and trimethylbenzenes to produce xylenes, in a reaction zone comprising at least two catalytic beds each comprising a different catalyst, one of the catalysts containing at least one zeolite with mordenite type structure, at least partially in its acid form, and the other catalyst containing at least one zeolite with mazzite type structure, at least partially in its acid form, each catalyst containing at least one matrix and, optionally, at least one element selected from the group formed by groups IB and VIII of the periodic classification of the elements.
