Claim 0:
1. A hydrogenolysis process wherein a hydrocarbon-based feedstock comprising aromatic compounds having at least 8 carbon atoms is treated by means of an introduction of hydrogen and in the presence of a catalyst, to convert C2+ alkyl chains of said aromatic compounds into methyl groups and to produce a hydrogenolysis effluent enriched in methyl-substituted aromatic compounds,
wherein the hydrogenolysis process is carried out with the following operating conditions:
temperature of between 300° C. and 550° C.;
pressure of between 0.1 and 3 MPa;
H2/HC molar ratio of between 1 and 10;
WWH of between 0.1 and 50 h−1, and

wherein the catalyst comprises a support comprising at least one refractory oxide, and an active phase comprising nickel and molybdenum, wherein:
the nickel content is between 0.1 and 25% by weight relative to the total weight of the catalyst;
the molybdenum content is between 0.1 and 20% by weight relative to the total weight of the catalyst; and
the catalyst comprises a molar ratio of molybdenum to nickel (Mo/Ni) of between 0.2 and 0.9.
