Studying the radiation resistance of synthetic oils obtained from petroleum bitumen rocks
Abstract
The results of studies of the radiation impact on artificial oil from the oil-bitumen rock of the Kirmaku field in Azerbaijan are presented. Petroleum bitumen rock is a natural material formed from oil in the upper layers of the earth's crust as a result of the evaporation of light fractions from it, the natural deasphalting of oil and the processes of interaction of its components with oxygen. From 375 g of bitumen rock, 50 ml of synthetic oil was obtained by distillation on a Retort Heating Jacket at a temperature of 950 F (510 C). The formation of gases and changes in the properties of liquid residues during the processing of artificial oil obtained in laboratory conditions have been studied, as well as the radiation resistance of various fractions of oil from bitumen rock has been studied.The studies were carried out under the influence of γ-radiation Co60 MRKH-γ-30 in a wide range of absorbed doses (43‒216 kGy) in air and vacuum. at dose rate Р=0.5 Gy/s. The results of chromatographic, chromatospectroscopic and IR spectroscopic studies of artificial oil samples are presented. The results of such studies make it possible to evaluate the possibility of obtaining petroleum products for various purposes using the radiation-thermal method from oil-bitumen rock, as well as the use of these materials to isolate radioactive sources from the environment.
