Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
