A process for upgrading low octane naphthas to produce gasoline products with low levels of benzene and aromatics while retaining a high pool octane uses a paraffinic naphtha reformer feed which is dehexanized to provide a C.sub.7 + fraction which is fed to the reformer and a C.sub.6 fraction which is fed together with the C.sub.6 fraction from the reformer effluent to a catalytic upgrading step where the low octane components from the naphtha and the benzene from the reformate are converted to a low benzene, high octane gasoline by alkylation of the benzene and other aromatics present in the reformate. The process has the advantage that benzene make in the reformer is reduced by the partial by-passing of the C.sub.6 benzene precursors around the reformer; in addition, improved benzene alkylation results from the presence of additional light olefins generated by the cracking of paraffins from the paraffinic naphtha. the reaction is preferably carried out in a turbulent fluidized bed reaction zone.
