This patent describes a fixed bed process for the alkylation of reformate comprising C{sub 6{minus}} hydrocarbons to produce high octane gasoline. It comprises: separating a naphtha feedstream by fractionation into a lower boiling fraction comprising iso-C{sub 6} aliphatic hydrocarbon components and a reformer feedstock fraction comprising higher boiling C{sub 6+} aliphatic hydrocarbon components; reforming the reformer feedstock fraction comprising the higher boiling C{sub 6+} aliphatic components in contact with reforming catalyst and under reforming conditions to produce a reformate containing benzene and C{sub 7+} hydrocarbons; separating the reformate into a C{sub 6{minus}}hydrocarbon stream containing benzene and paraffins and a C{sub 7+} hydrocarbon stream; introducing the C{sub 6 {minus}} hydrocarbon stream and alkylating agent into an alkylating zone in contract with acidic metallosilicate catalyst under alkylating condition whereby benzene is alkylate to produce high octane gasoline containing C{sub 7+} aromatic hydrocarbons.
