Abstract:
The present invention relates to a device and a process for converting aromatic compounds, wherein: methyl-substituted aromatic compounds are extracted from a hydrocarbon feedstock (2) comprising aromatic compounds having at least 8 carbon atoms in an extraction unit (1), to produce at least one effluent enriched in methyl-substituted aromatic compounds (3A, 3B) and an effluent depleted in methyl-substituted aromatic compounds (4); and C2+ alkyl chains of the aromatic compounds of the depleted effluent (4) are converted into methyl groups in a hydrogenolysis unit (5) placed downstream of the extraction unit (1), to produce a hydrogenolysis effluent enriched in methyl-substituted aromatic compounds (7).
