ABSTRACT:
A straight-run naphtha is fractionated at about 66.degree. C., which is just below the boiling point of methylcyclopentane. The 66.degree. C.+ fraction is reformed, and at least a portion of the reformate combined with the 66.degree. C.- fraction and reacted under aromatization conditions over a ZSM-5-type catalyst to form a C.sub.5 + product rich in aromatics. The C.sub.5 + aromaticized product and the remaining reformate can be either sent for BTX recovery or used as a high-octane component of a gasoline blending pool.
