One exemplary embodiment can be an ion-exchanged xylene isomerization catalyst. The ion-exchanged xylene isomerization catalyst can include:

Aromatic isomerization catalyst and a process of use thereof

This invention embodies a catalyst and a process for transalkylation of C, C, and Caromatics to obtain a high yield of xylenes. The catalyst comprises a novel UZM-14 catalytic material comprising globular aggregates of crystallites having a MOR framework type with a mean crystallite length parallel to the direction of the 12-ring channels of about 60 nm or less and a mesopore volume of at least about 0.10 cc/gram. The UZM-14 catalyst is particularly active and stable in a transalkylation process.

Transalkylation process

Processes for making xylene employ catalysts containing rhenium and a molecular sieve component comprising an acidic MFI molecular sieve having a Si/Almolar 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.

Xylene production processes employing rhenium-containing catalysts

Transalkylation catalysts containing rhenium and a molecular sieve component comprising an acidic MFI molecular sieve having a Si/Almolar ratio of less than about 80 and mordenite provide a transalkylation product with a low content of benzene co-boilers. The invention encompasses sulfided catalyst embodiments and methods of making the catalysts.
