摘要: Disclosed are a catalyst system and its use in process for the conversion of feedstock containing C 8 + aromatic hydrocarbons to produce light products, comprising benzene, toluene xylene. The comprises (a) first bed composition, said composition zeolite having constraint index 3 12 combined (i) optionally with at least one metal Group 10 IUPAC Periodic Table, (ii) second 11 15 Table; (b) meso-mordenite zeolite, (iii) wherein is synthesized from TEA or MTEA mesopore surface area greater than 30 m 2 /g agglomerates composed primary crystallites, crystallites have an average crystal size as measured by TEM less 80 nm aspect ratio 2.
