ABSTRACT:
Concentrations of straight chain material are material are increased by treating a thermal-cracked oil distillate boiling in the range of 120.degree. to 290.degree. C. and containing aliphatic olefins, at a temperature of 0.degree. to 330.degree. C. in liquid phase in the presence of an acid catalyst, said thermal-cracked oil distillate being obtained from a thermal cracking process of thermally cracking a petrolic heavy residual oil at a temperature not lower than 400.degree. C. and not exceeding 700.degree. C.; and then separating and removing from the reaction mixture heavy components boiling higher than said distillate.
