Patent ID: 8366909

Claim:
A reforming process comprising: a. contacting a naphtha boiling range feedstock in a penultimate stage of a multistage reforming process at a first reforming pressure with a catalyst comprising a low acidity beta zeolite and a Group VIII metal to produce a penultimate effluent; and b. contacting at least a portion of the penultimate effluent in a final stage of the multi-stage reforming process at a second reforming pressure and conditions sufficient to increase the amount of aromatics and thereby increase the RON with a catalyst comprising high silica ZSM-5 and a Group VIII metal to produce a final effluent, with the ZSM-5 having a SiO 2 :M 2 O 3 molar ratio of at least 200:1, where M is Al, B, Ga or combinations thereof, and with the ZSM-5 having at least 90% of its acid sites neutralized.
