A process for ethylbenzene conversion and xylene isomerization of an alkylaromatic feed mixture is described. A Calkylaromatic feed mixture can be contacted with two catalyst beds successively in the liquid phase in a Caromatic hydrocarbon isomerization zone. The first catalyst comprises a passivated zeolite containing a ten-membered ring channel framework for the conversion of ethylbenzene. The second catalyst comprises UZM-54 zeolite for selective isomerization of the xylenes.

Two bed liquid phase isomerization process

It is desirable to provide improved processes and apparatuses for methylation of aromatic compounds such as toluene and benzene in an aromatics complex. Described herein are processes and apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, processes and apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex.
