Abstract

Methods and corresponding catalysts are provided for conversion of an aromatic feed containing C8+ aromatics (particularly C9+ aromatics) to form a converted product mixture comprising, e.g., benzene and/or xylenes. The aromatic feed can be converted in the presence of a catalyst that includes a silica binder, a mixture of a first zeolite having an MEL framework (such as ZSM-11 and/or an MFI framework (such as ZSM-5), and a second zeolite having an MOR framework, such as mordenite, particularly a mordenite synthesized using TEA or MTEA as a structure directing agent, and a metal. The catalyst can further include one or more metals supported on the catalyst.
