Abstract
This invention is drawn to a process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene which contain a substantial concentration of nonaromatics using a catalyst system which features the ability to both convert nonaromatics and to obtain an improved yield of para-xylene from the mixture relative to processes of the known art.
