Abstract
A process combination is disclosed to selectively upgrade naphtha to obtain products suitable for further upgrading to reformulated fuels. A naphtha feedstock is hydrogenated to saturate aromatics, followed by selective isoparaffin synthesis to yield light and heavy naphtha and isobutane; isobutane and isopentane in the product are obtained in superequilibrium concentrations. The heavy 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.
