ABSTRACT:
A process is provided for the production of xylenes from reformate. The process is carried out by methylating the benzene, toluene, or both present in the reformate to produce a resulting product having a higher xylenes content than the reformate. Greater than equilibrium amounts of para-xylene can be produced by the process.
