Popis: The oil investigated was obtained in a continuous pilot unit for adsorptive treatment of a heavy coker gasoil, produced in a commercial delayed coking unit from medium-sulfur feed. The radiational and thermal stability of the constituent hydrocarbons and individual groups of compounds was evaluated from the changes of their content in the oil after gamma irradiation from a cobalt 60 source. Chemical group composition was determined chromatographically. Resinous compounds were least resistant to radiation. The resistance of the organosulfur components was dependent on molecular structure; benzothiophene and dibenzothiophene contents were increased by irradiation from the conversion of naphthenobenzothiophenes.
