ABSTRACT:
A process combination is disclosed to selectively upgrade naphtha to obtain gasoline which is in accordance with current standards for reformulated fuels. A naphtha feedstock is fractionated to selectively direct light naphtha to isomerization or blending, a heart-cut fraction to reforming, and a heavy portion to selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy portion of the synthesis naphtha is processed by reforming. Light naphtha may be isomerized, with or without recycle of low-octane components of the product. A gasoline component is blended from light, synthesis, and reformate products from the process combination.
