Abstract

A process for reducing the benzene content of gasoline stream, such as a reformate or light naphtha, comprises alkylating the gasoline stream in a reaction zone with an olefin alkylating agent. A paraffinic stream comprising C5 to ClO paraffins is fed to the inlet of the alkylation reaction zone.
