  • Patent number: 5658453
    Abstract: A process combination is disclosed to selectively upgrade naphtha in a manner to obtain an aromatics-rich, low-olefin product from the combination. Preferably the naphtha is subjected to aromatization to obtain an aromatics concentrate which is upgraded by hydrogenation of olefins in the aromatics-rich stream. Olefin saturation is effected following separation of the major portion of hydrogen from the aromatics concentrate and before fractionation/stabilization for removal of light ends, with concomitant low saturation of aromatics and with removal of light ends in a fractionator which would be associated with the aromatization in any case.
