Abstract

See full text

A straight-run naphtha is fractionated into a light naphtha fraction and a heavy naptha fraction containing methylcyclopentane and heavier hydrocarbons. The heavy fraction is reformed and the C.sub.5 -C.sub.6 paraffin portion of the reformate combined with the light naphtha fraction for isomerization. The heavy reformate is converted over a ZSM-5-type catalyst to produce a product enriched in aromatics which may be sent for BTX recovery or to a gasoline pool as a high-octane gasoline blending stock.
