1. A method for converting a feedstock comprising C8+ aromatics, comprising:
contacting the feedstock and optionally hydrogen with a catalyst composition under conversion conditions in a reactor comprising at least one fixed catalyst bed of the catalyst composition to produce a converted product mixture,
wherein the catalyst composition comprises:
(i) a zeolite mixture comprising ZSM-11, and ZSM-5, wherein a SiO2/Al2O3 molar ratio of the ZSM-5 is greater than or equal to 21:1, wherein a weight ratio of the ZSM-11 and the ZSM-5 is 0.3 to 0.6;
(ii) a combination of a first metal in Groups 7-10 and a second metal in Groups 2, and 11 to 15 in the Periodic Table of Elements; and
(iii) a silica binder, wherein the silica binder comprises a mixed silica.
