The study has been<br />conducted on a 60Co gamma_source at a dose rate of P = 0.5 Gy/s and various absorbed doses of<br />D = 43–216 kGy. Samples of synthetic oil from natural bitumen rocks have been analyzed by<br />chromatography, gas chromatography–mass spectrometry, and IR -spectroscopy, and their<br />radiation resistance has been evaluated. The results of the study allow for bothassessment of the<br />feasibility of manufacturing petrochemicals for various applications by radiation processing and<br />use of these materials for isolating radioactive sources to preclude their impact on the<br />environment.<br />Oil–bitumen rock (OBR) is a natural material formed from crude oil in the upper layers<br />of the Earth crust as a result of the slow evaporation of light fractions from the oil, natural oil<br />deasphalting, and the processes of interaction of its components with oxygen and sulfur.<br />According to UN estimates, the world’s geological reserves of OBR amount to ~360 billion tons<br />on the hydrocarbon (HC) basis and are an alternative source of HC feedstock. The object of<br />investigation was the synthetic oil derived from OBR of the Balakhany field of Azerbaijan.<br />Experiments were carried out on an MRKh γ-30 60Co gamma-ray source at a dose rate of 0.5<br />Gy/s. By distillation in a Retort Heating Jacket apparatus at a temperature of 950 F (510°C), 50<br />mL of synthetic crude was obtained from 375 g. The rock composition (%) was as follows: oil<br />22, water 6, sand 72. Samples of synthetic oil were irradiated to different absorbed doses in the<br />range of 43–216 kGy in air or vacuum to follow the kinetics of the processes and to reveal the<br />role of oxygen in the radiation resistance of the OBR.The samples of the synthetic oil intended<br />for chromatographic analysis were dried with anhydrous sodium sulfate (Na2SO4) and diluted<br />with dichloromethane (СН2Cl2); mass chromatograms in the m/z range of 35–400 (m/z is the ion<br />mass to charge ratio) were recorded on a GCMS Trace DSQ instrument (Thermo Electron,<br />Finnigan USA, 2005); and components of the samples were identified by the spectra.<br />The sample notation was as follows: 12169, the initial synthetic oil; 12170, the synthetic<br />oil irradiated for 96 h in air; and 12171, the synthetic oil irradiated for 96 h in a vacuum. IR<br />spectra of the samples were recorded on an M-80 spectrophotometer in the wave number range<br />of 700–4000 cm–1. The gaseous products were analyzed by gas chromatography.<br />The relatively high radiation resistance of the synthetic oil, recovered from the OBR, in<br />vacuum and air below 50°C is associated with the presence of paraffins, polynuclear aromatic<br />hydrocarbons, and resin asphaltene substances in its composition. This makes it possible to use<br />the synthetic oil as a feedstock for manufacturing a waterproof material applicable in radiation<br />fields, including the disposal of radioactive waste. The organic matter of the OBR may serve as a<br />promising source material for manufacturing various fuels, lubricating oils, coke, and asphalt.<br />Hydrogen, hydrocarbon gases, and olefin hydrocarbons can be produced from the synthetic oil<br />by the joint ionizing radiation and heat treatment at consistent values of the temperature and the<br />dose rate.</p></dc:description> <dc:source>The International Conference dedicated to the 55th anniversary from the foundation of the Institute of Chemistry of the Academy of Sciences of Moldova () 180-180</dc:source> <dc:title>Radiation-chemical conversion of oil derived from oil bitumen rock </dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> </oai_dc:dc>
