Abstract
The invention relates to a selective hydrogenolysis method for treating a feed rich in aromatic compounds having more than 8 carbon atoms, comprising transforming at least one alkyl group with at least two carbon atoms (ethyl, propyl, butyl, isopropyl, etc.) attached to a benzene ring into at least one methyl group. The invention also relates to the integration of the hydrogenolysis unit into an aromatic complex.
