摘要
Disclosed are catalyst compositions and their 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 zeolite which comprises a MOR framework structure and a MFI and/or MEL framework structure, (b) at least one first metal of Group 10 of the IUPAC Periodic Table, and (c) optionally at least one second metal of Group 11 to 15 of the IUPAC Periodic Table. In one or more embodiments, the MOR framework structure comprises mordenite, preferably a mordenite zeolite having small particle size. The MFI framework structure preferably comprises ZSM-5, and the MEL framework structure preferably comprises ZSM-11.
