ABSTRACT:
A process is disclosed for upgrading reformate and/or light FCC gasoline by substantially reducing the amount of benzene in the gasoline product while simultaneously reducing the gasoline ASTM distillation End Point. The process comprises the fractionation of reformate to recover that fraction, C.sub.7 -C.sub.8 hydrocarbons, directly useful in gasoline without further conversion. A heavy bottom fraction comprising C.sub.9 + aromatic and non-aromatic hydrocarbons is recovered and a C.sub.6 fraction rich in benzene. The total C.sub.6 fraction and a portion of the C.sub.9 + fraction are converted by alkylation, transalkylation and cracking in contact with acidic metallosilicate catalyst particles to gasoline boiling range materials rich in alkylaromatics. Following debutanization or depentanization of the conversion product, the fraction containing unconverted benzene is recycled to the reformate fractionator.
