ABSTRACT OF THE DISCLOSURE A heat soaked polymer by-product from the production of gasoline using a 90-400°F. steam cracker naphtha as feed is converted to an aromatic hydrocarbon oil or to a naphthenic hydrocarbon oil by first subjecting the same to a thermal polymerization and then subjecting the thermal polymerization product to a hydrotreating or hydrogenation step or both. Generally, the hydrotreatment is accomplished at relatively mild conditions so as to avoid any change in aromatic ring structure. Hydrogenation, on the other hand, is accomplished at more severe conditions so as to effect hydrogenation of the aromatic rings.
