【 摘 要 】

The possibility of obtaining bitumen of improved quality from oil mixtures of the newly developed Vankor and West Siberian fields of variable composition was described in the article. The optimal hydrocarbon composition of raw materials was formed and the technological parameters of the oxidation process were selected to obtain improved bitumen of sonochemical activation, which provided high plasticity and thermal stability of bitumen while maintaining low-temperature properties. The group hydrocarbon composition of tars was determined by the method of liquid-adsorption chromatography with gradient displacement. The fuel oil sample obtained during the processing of given oils and oil residues of different oil fractions sampling depth was used for carrying out the research. The obtained cubic residues were oxidized at a laboratory unit for production of oxidized petroleum bitumen under conditions of sonochemical activation simulating the technology of obtaining oxidized bitumen under industrial conditions. The loading of the laboratory cube for oxidation was 2,8 kg of tar, experiments were carried out under the following conditions: temperature 2502 C, air flow 4,00,1 l∗min/kg with periodic sampling for monitor the quality of the oxidized product at the softening temperature.
