ABSTRACT:
This invention provides a method of processing thermal cracked by-product oil which comprises reacting a distillate from a thermal cracked by-product oil principally containing components of a boiling range between 75.degree. C. and 198.degree. C. said distillate being one of the distillates from the cracking of petroleum hydrocarbons at a cracking temperature of 700.degree. C. or higher, and containing a ratio of 5-100 molar percent aromatic olefins to non-olefinic aromatic hydrocarbons, in liquid phase in the presence of an acid catalyst under such conditions that the reaction temperature is 0.degree. C.-200.degree. C., the liquid residence time is 0.1 hour-5 hours and wherein the content of aromatic olefins in the reaction system are 5% by weight or less at the end of the reaction, to yield a processed distillate containing non-condensed di- and tricyclic aromatic compounds which are reaction products of aromatic olefins with other aromatic hydrocarbons but no substantial amount of unsaturated components.
