Xylene Production Processes Employing Rhenium-Containing Catalysts

摘要

Processes for making xylene employ catalysts containing rhenium and a molecular sieve component comprising an acidic MFI molecular sieve having a Si/Al₂ molar ratio of less than about 80 and mordenite to provide a transalkylation product with a low content of benzene co-boilers. The invention encompasses the use of sulfided catalyst embodiments in xylene production processes.
