F-4589 METHOD FOR SUPPRESSING HYDROGENOLYSIS OF MOBLE METAL/LOW ACIDITY ZEOLITES USED IN AROMATIZING PARAFFINS Abstract A process for converting a C6-C12 paraffinic hydrocarbon feed to aromatics by contacting the feed with a noble metal/low acidity medium pore size zeolite catalyst in a conversion zone by modifying the noble metal component of the catalyst to its sulfide form by either presulfiding the catalyst or adding at least one of H2S, SO2 or an organic sulfur compound to the feed in an amount effective to suppress hydrogenolysis and increase aromatic selectivity of the catalyst.
