Abstract
Methods and corresponding catalysts are provided for conversion of an aromatics 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 mixture of a first zeolite having an MEL framework, such as ZSM-11, and a second zeolite having a MOR framework, such as mordenite, particularly a mordenite synthesized using TEA or MTEA as a structure directing agent. The weight ratio of the first zeolite to the second zeolite in the catalyst can be from 0.3 to 1.2, or from 0.3 to 1.1, or from 0.3 to 1.0. The catalyst can further include one or more metals supported on the catalyst, such as a combination of metals.
