Abstract:
The present invention relates to a method for converting a feed mixture comprising an aromatic C8 mixture of xylenes and ethylbenzene in which the para-xylene content of the xylene portion of the feed is less than equilibrium to produce a product mixture of reduced ethylbenzene content and a greater amount of para-xylene, which method comprises contacting the feed mixture at conversion conditions with a first catalyst having activity for the conversion of ethylbenzene, and with a second catalyst having activity for the isomerization of a xylene.

Claim (Index 1):
A process for isomerizing a feed stream comprising xylenes and ethylbenzene, the process comprising:\n contacting the feed stream with a first catalyst in a dual-bed catalyst system to produce a first effluent stream; and contacting the first effluent stream with a second catalyst in the dual-bed catalyst system to produce a second effluent stream, wherein the first catalyst comprises an aluminosilicate molecular sieve with up to 0.8 weight percent aluminum, wherein the first catalyst has activity for the conversion of ethylbenzene, wherein about 20 percent or more of the ethylbenzene in the feed stream is converted to hydrocarbons other than ethylbenzene, and wherein EBC/Xylene Loss is at least 45 when about 30 percent of the ethylbenzene is converted.
