Definition
Distillates (petroleum), heavy thermal cracked is a complex combination of hydrocarbons from the distillation of the products from a thermal cracking process. It consists of unsaturated hydrocarbons having carbon numbers predominantly in the range of C15 through C36 and boiling in the range of approximately 260.degree.C to 480.degree.C (500.degree.F to 896.degree.F). This stream is likely to contain 5 wt.% or more of 4- to 6-membered condensed ring aromatic hydrocarbons.
