Abstract
Process for the isomerization of a xylene feedstock employing a silicalite catalyst. A xylene feedstock containing a mixture of xylene isomers and ethylbenzene is passed to a reaction zone containing the silicalite catalyst. Para-xylene is present in the feedstock in less than an equilibrium amount, and ethylbenzene is present in a concentration greater than the para-xylene concentration. Hydrogen and/or water are also supplied to the reaction zone. The reaction zone is operated under conditions to effect isomerization of xylene isomers to provide an increased para-xylene content, and disproportionation of ethylbenzene to provide a decreased ethylbenzene content.
