Abstract: An improved process is disclosed for ethylbenzene and xylene isomerization in a non-equilibrium mixture of xylenes and ethylbenzene. By addition of trace quantities of water to the reaction zone, equivalent isomerization is effected at lower temperatures wherein benefits could be realized in reduced losses and improved catalyst life.
