A heavy aromatics feed is converted to lighter aromatics products, such as benzene, toluene and xylenes by contacting a C9+ aromatics fraction and benzene and/or toluene over a catalyst comprising a zeolite, such as ZSM-12, and a hydrogenation component, preferably platinum. The catalyst, complete w...
