A method in which the catalytic hydrodealkylation of a hydrocarbon composition comprising a C 8 -C 13 alkyl aromatic compound, which may be in a mixture with C 4 -C 9 aliphatic and alicyclic products, is carried out alone. Wherein the hydrocarbon composition is a catalyst comprising ZSM-5 zeolite modified with at least one metal belonging to groups IIB, VIB and VIII and having a molar ratio Si / Al in the range of 5 to 35; A temperature in the range of 700 ° C., a pressure of 2-4 MPa, a molar ratio of water to charge in the feed to the reactor in the range of 0.0006-0.16 (ie 0.01-2.5% w / w), and 3-6 a molar ratio H 2 / charge, comprises continuously in the presence of water, said method.
