Method for converting heavy reformate to BTX on metal-impregnated ZSM-5 and mesoporous mordenite zeolite composite catalyst

摘要

A method of producing a BTX (benzene, toluene, xylene) compound by feeding a heavy reformate stream to a reactor, wherein the reactor comprises a complex zeolite catalyst containing a mixture of desilicated mesoporous mordenite and ZSM-5, , The desiliconized mesoporous mordenite, ZSM-5, or both, comprise one or more impregnated metals. The composite zeolite catalyst can simultaneously catalyze an alkyl exchange reaction and a dealkylation reaction to prepare a BTX compound.
