摘要：
A catalyst system suitable for the isomerization of a xylene and conversion of ethylbenzene in a feed containing xylene and ethylbenzene comprising a first catalyst having activity for the conversion of ethylbenzene, a second catalyst having hydrogenation activity and a third catalyst having activity for the isomerization of a xylene where the second catalyst is located in the system between the first and third catalysts relative to a flow of feed material through the catalyst system.
