Abstract

The dual-zeolite catalyst for production of ethylbenzene is formed by mixing at least two different zeolites selected from mordenite, beta, ZSM-5, ZSM-11, ZSM-12, ZSM-22, ZSM-23, MFI topology zeolite, NES topology zeolite, EU-1, SAPO-5, SAPO-34, SAPO-11 and MAPO-36 zeolites and an inactive alumina binder. The two zeolites have different topology and possess dissimilar and unique physical and chemical characteristics, including particle size, surface area, pore size and acidity. The preferred amount of the two zeolites may range from 10 to 90 wt % of the total catalyst amount in the final dried and calcined form, preferably the zeolites are in equal parts by weight.
