Abstract

A process for reforming a full boiling range naptha feed to enhance benzene yield is disclosed which first separates the feed into a .[.C.sub.6 .]. .Iadd.lighter .Iaddend.fraction .[.containing at least 10% by volume of C.sub.7+ hydrocarbons.]. .Iadd., comprising at least one member selected from the group consisting of C.sub.6, C.sub.7, and C.sub.8 hydrocarbons, .Iaddend.and a .[.C.sub.7 +.]. .Iadd.heavier .Iaddend.fraction, then subjecting the .[.C.sub.6 .]. .Iadd.lighter .Iaddend.fraction to a catalytic aromatization process .[.and subjecting the C.sub.7 + fraction to a catalytic reforming process, followed by recovering the aromatics produced.]..Iadd.in the presence of a non-acidic catalyst.Iaddend..
