A hydrocarbon conversion process comprises: (1) contacting a hydrocarbon feed such as, for example, gasoline, with a catalyst under a sufficient condition to effect the conversion of the hydrocarbon to a product stream comprising aromatic hydrocarbons and olefins; (2) separating the product stream into a lights fraction comprising primarily hydrocarbons less than 6 carbon atoms per molecule, a middle fraction comprising C.sub.6 -C.sub.8 aromatic hydrocarbons and non-aromatic hydrocarbons, and a C.sub.9 + fraction comprising aromatic compounds; (3) separating the C.sub.6 -C.sub.8 aromatic hydrocarbons from the middle fraction; and (4) separating hydrocarbons containing 5 or more carbons per molecule (C.sub.5 + hydrocarbons) from the lights fraction. The C.sub.5 + hydrocarbons can be combined with the hydrocarbon feed. The non-aromatic hydrocarbons can also be converted to olefins by a thermal cracking process. Furthermore, the middle fraction can also be obtained by reforming naphtha.

[ That which is claimed is:] [1.] A process comprising:(1) contacting a hydrocarbon feed stream with a catalyst under a sufficient condition to effect the conversion of said hydrocarbon to a product stream comprising aromatic hydrocarbons and olefins wherein said hydrocarbon feed stream comprises at least one non-aromatic hydrocarbon;(2) separating said product stream into a lights fraction, a middle fraction comprising C.sub.6 -C.sub.8 aromatic hydrocarbons and non-aromatic hydrocarbons, and a C.sub.9 + fraction comprising aromatic compounds; and(3) separating said C.sub.6 -C.sub.8 aromatic hydrocarbons from said non-aromatic hydrocarbons thereby producing a non-aromatic hydrocarbons fraction.
