ABSTRACT:
A reforming-isomerization process for realizing optimum upgrading of a naphtha feedstock is disclosed. The feedstock is reformed over a bimetallic catalyst and the reformate is separated into one or more gas fractions, a C.sub.5 -C.sub.6 paraffin liquid fraction and a reformate liquid product. The C.sub.5 -C.sub.6 fraction is isomerized to upgrade the C.sub.5 -C.sub.6 components and the isomerizate is separate into a light gas product and a C.sub.5 -C.sub.6 isomerizate liquid product with optional separation and recycle of normal paraffins. The light gas products are compressed and recycled for use in the reformation and isomerization. The C.sub.5 -C.sub.6 isomerizate is blended with the reformate liquid product to produce high octane motor fuel.
