Para- In the production process of the xylene, the feed stream containing the C 6+ aromatic hydrocarbon is separated into a C 7- aromatic hydrocarbon-containing stream, C 8 aromatic hydrocarbon-containing stream and a C 9+ aromatic hydrocarbon-containing stream. The 7- C is an aromatic hydrocarbon-containing stream is contacted with a methylating agent to call the toluene with xylene and generates the methylation effluent stream. Ethylbenzene is C 8 is removed from an aromatic hydrocarbon containing stream, para- to produce a stream of xylene depleted-xylene is para-is recovered from the ethylbenzene depleted C 8 aromatic hydrocarbon-containing stream and the methylation effluent stream from the xylene recovery section para and, then the para-xylene depleted stream, the para-xylene into contact with the xylene in the xylene depleted stream, under effective liquid phase conditions to generate an isomerized stream to the isomerization isomerization catalyst. C 9+ aromatic stream C 9+ by converting an aromatic a C 8- aromatics into contact with the transalkylation catalyst under conditions effective to produce a transalkylation stream, the transalkylation stream is para with the isomerized stream-xylene recovery It is recycled to the section.
