PRODUCTION OF PETROLEUM BITUMEN BY OXIDATION OF TAR FROM A MIXTURE OF EASTERN UKRAINIAN OILS
The study results of the process obtaining of petroleum bitumen with improved quality indicators are described. The method of mixing the tar of paraffinic oils with the residue and the distillation of Orkhiv oil with subsequent oxidation of this mixture was used. To conduct the research, tar extracted from Western Ukrainian paraffinic oils was used. The influence of temperature, oxidation duration and air consumption on the operational properties of oxidized petroleum bitumens were determined.
