Title:
２床液相異性化プロセス
Document Type and Number:
Japanese Patent JP7411813
Kind Code:
B2
Abstract:
A process for ethylbenzene conversion and xylene isomerization of an alkylaromatic feed mixture is described. A C8 alkylaromatic feed mixture can be contacted with two catalyst beds successively in the liquid phase in a C8 aromatic 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.
