Abstract

Disclosed is a catalyst composition and its use in a process for the conversion of a feedstock containing C8+ aromatic hydrocarbons to produce light aromatic products, comprising benzene, toluene and xylene. The catalyst composition comprises a mordenite zeolite synthesized from TEA or MTEA, optionally at least one first metal of Group 10 of the IUPAC Periodic Table, and optionally at least one second metal of Group 11 to 15 of the IUPAC Periodic Table, wherein said mordenite zeolite has a mesopore surface area of greater than 30 m2/g and said mordenite zeolite comprises agglomerates composed of primary crystallites, wherein said primary crystallites have an average primary crystal size as measured by TEM of less than 80 nm and an aspect ratio of less than 2.
