ABSTRACT OF THE DISCLOSURE High-purity C7 and/or C8 aromatic hydrocarbons are pro- duced by reforming a C7 or C8 full boiling carbon number naphtha feed fraction or combinations thereof under reforming conditions of sufficient severity to convert essentially all of the non- aromatic portion of the naphtha feed boiling in the C7 to C8 aromatic boiling range to C7 and/or C8 aromatics, and then separa- ting the reformate by fractional distillation into high-purity fractions of C7 and/or C8 aromatic hydrocarbons. Preferably, the C7 and/or C8 full boiling carbon number naphtha feed fraction is reformed in a plurality of reformer reaction stages with increas- ingly more severe conditions in order to maximize the yield of the C7 and C8 aromatics.
