Abstract 1. A PROCESS COMPRISING CONTACTING A GASOLINE BOILING RANGE VIRGIN NAPHTHA WITH A CATALYST CONSISTING ESSENTIALLY OF ZSM-5 TYPE OF ALUMINO-SILICA ZEOLITE HAVING A HYDROGENATION/DEHYDROGENATION COMPONENT THEREIN IN ADMIXTURE WITH ADDED HYDROGEN IN A HYDROGEN TO HYDROCARBON RATIO OF ABOUT 1 TO 10, AT ABOUT 600 TO 800*F., 50 TO 1000 P.S.I.G. AND 0.5 TO 10 WHSV, UNDER SUCH COMBINATION OF CONDITIONS AS TO HYDROCRACK AT LEAST ABOUT 40 WT. PERCENT OF SAID VIRGIN NAPHTHA TO PENTANE AND LIGHTER PRODUCTS HAVING A C3 TO C4 RATIO OF ABOUT 1.0 TO 1.4, AND AN N-C4 TO I-C4 RATIO OF ABOUT 0.85-1.2; WHICH PROCESS ALSO PRODUCES UP TO ABOUT 60 WT. PERCENT OF A C6+ LIQUID PRODUCT HAVING A MINIMUM CLEAR RESEARCH OCTANE NUMBER OF ABOUT 80, WHICH LIQUID PRODUCT HAS AN OCTANE NUMBER OF AT LEAST ABOUT 40 UNITS HIGHER THAN SAID FEED.
