PROCESS FOR AROMATISATION OF HYDROCARBON FEEDSTOCK USING ZINC-CONTAINING ZEOLITES WHILE AVOIDING ZINC DEPLETION

摘要

A process for converting a C2-C12 non-aromatic hydrocarbon feed to aromatics by contacting the feed with a zinc-containing medium pore size zeolite catalyst in a conversion zone, comprising adding at least one non-metal oxide or sulfide to the feed in an amount effective to prevent elution of zinc from the zinc-containing zeolite catalyst.
