Abstract
In work the impact of ionizing radiation on mixes hexane- hexenе was investigated. Laboratory researches were conducted on a gamma source <sup>60</sup>Co at the power of dose of P=0.10 of Gy / s in intervals of the absorbed doses D=34-103 kGy. Impact of ionizing radiation on structural and group composition of mix hexane- hexene in static conditions was investigated. Density, viscosity, iodic numbers of mixes hexane- hexenе were determined. before radiation at various absorbed doses. Existence of olefin connections is the main reason for small stability in hydrocarbon fuels. Studying of radiolysis of mixes of saturated and nonsaturated hydrocarbons at various concentration gives the chance to draw conclusions about the nature of the main radiochemical processes. In the fuels containing a large amount of nonsaturated hydrocarbons in the course of radiation the coking behavior increases and color worsens. Structuring is physically shown in organic liquids in change of viscosity and density. The processes which arose in connection with radiolysis for a long time develop after the radiation termination that can lead to change of composition of fuel. As a result of it at ambient temperature operational properties of oil fuels worsen. Communication between the chemical composition of fuel and its stability is still insufficiently well studied. These experiments continue for the purpose of studying of impact of ionizing radiation on changes of physical and chemical properties of hydrocarbons of oil.
Highlights
The main reason of hydrocarbon fuels low stability is the presence of olefinic compounds
We studied several operational performance of fuel under static conditions in the usual manner before and after irradiation
The aim of the work is the study of radiation resistance of hexane-hexene mixtures were determined before and after irradiation at various absorbed doses
Summary
The main reason of hydrocarbon fuels low stability is the presence of olefinic compounds. The processes that have arisen in connection with radiolysis continue for a long time after the cessation of irradiation, which can lead to a change in the composition of the fuel. At ambient temperature, the performance properties of petroleum fuels deteriorate. The relationship between the chemical composition of the fuel and its stability is not well understood. These experiments continue to study the effect of ionizing radiation on changes in the physico-chemical properties of petroleum hydrocarbons. Stability is understood as the ability of a fuel to maintain its chemical structure under operating conditions with a change in temperature, ionizing radiation and under the influence of metals. It is necessary to provide a radiation resistance in the physical and chemical properties of the fuel
