A process for producing a high octane gasoline having an octane number of at least 87 (RON + 0), which comprises hydrocracking a highly aromatic, substantially dealkylated hydrocarbon feed produced by the catalytic cracking of a hydrocarbon fraction, the feed having an initial boiling point of at least 300/sup 0/F, an aromatic content of at least 50 weight percent, and a hydrogen content not more than 12.5 weight percent at a hydrogen partial pressure of not more than 1000 psig and a conversion to a hydrocarbon fraction which has a boiling range which extends from the boiling point of a C/sub 5/ hydrocarbon to 385/sup 0/F., of not more than 50 vol. percent and numerically equal to not more than 0.05 times the hydrogen pressure (psig) to gasoline boiling range products, and recycling the fraction which is not converted during the hydrocracking to the catalytic cracking step.
