ABSTRACT:
A process for converting a C.sub.2 -C.sub.12 paraffinic hydrocarbon feed to aromatics comprising passing the feed through a first conversion zone wherein the feed contacts a noble metal/low acidity medium pore size zeolite catalyst, and then passing the resulting hydrocarbon mixture through a second conversion zone wherein the resulting hydrocarbon mixture contacts a medium pore size acidic zeolite catalyst.
