A process is provided for the disproportionation of a toluene feedstock over a metal promoted mordenite catalyst. The catalyst may contain between 1.0-1.5 weight percent nickel. The toluene feedstock is supplied to the reaction zone and into contact with the catalyst. The reaction zone is operated under disproportionation conditions. During disproportionation, heavy aromatic reformates, in concentration of at least 4 weight percent, are introduced into the reaction zone. Disproportionation product containing benzene and xylene is continuously withdrawn. The addition of the heavy aromatic reformate does not adversely affect toluene conversion rates, product selectivity to benzene, catalyst activity or catalyst life. Moreover, production of xylenes increase at the expense of production of heavies.
