ABSTRACT:
A process combination is disclosed to selectively upgrade catalytically cracked gasoline to obtain products suitable for further upgrading to reformulated fuels. A naphtha feedstock, preferably heavy naphtha, is hydrogenated to saturate aromatics, followed by selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy synthesis naphtha may be processed by reforming, light naphtha may be isomerized, and isobutane may be upgraded by dehydrogenation, etherification and/or alkylation to yield gasoline components from the process combination suitable for production of reformulated gasoline.
