Abstract
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.
