“…Although application of ionizing particles in petroleum industry has had a rapid growth during the recent decades, quite a few works have investigated the rheological property changes that are brought about because of radiation-induced reactions. Alfi et al − showed that electron-induced thermal cracking of heavy petroleum fluids results in products with lower viscosities than the thermal cracking cases.…”

Application of ionizing incidents, as an innovative way of combining engineering physics and chemistry to efficiently deliver energy to the electronic structure of the molecules, has introduced great opportunities to the developing oil and gas industry. Although heavy petroleum resources have been considered as a potential alternative to fulfill the growing energy inquiries, the lack of cost-effective technologies for extraction, transportation, or refinery upgrading hinders the development of heavy oil reserves. Nevertheless, electron irradiation technology can economically overcome principal problems of heavy oil processing arising from the heavy oil's unfavorable physical and chemical properties. This technology promises to increase the yields of valuable and environmentally satisfying products in thermal cracking. Electron particles were observed to reduce the viscosity of heavy deasphalted petroleum fluid and to provide a higher concentration of light hydrocarbons in the final product. This behavior is attributed to the intensified cracking in the presence of ionizing electrons. Molecular distribution of the hydrocarbons in liquid and gas products shows that although simultaneous application of heat and electron particles accelerates the cracking process, the reaction mechanism does not differ from that of thermal cracking. The results also demonstrate the substantial influence of reaction temperature and absorbed dose upon the radiolysis throughput. Moreover, aging analyses of the post-treatment samples proves the time-stable nature of the irradiation products.

Ionizing electron particles were used as an efficient means of delivering energy to heavy hydrocarbon molecules. Although heavy oil reserves are known as rich sources of energy, their contribution to the energy market has been impacted by the fact that the conventional thermal or catalytic upgrading and visbreaking methods always demand a considerable energy and money investment. Therefore, application of potential alternatives with lower operating costs and higher process throughput appears to be extremely crucial in such a competitive market. In this research, high-energy electron processing technology was offered as a remedy to reduce the viscosity of heavy petroleum samples. Irradiated fluids exhibited lower viscosities than thermally cracked samples. Moreover, reaction temperature was observed to have a substantial influence on radiolysis process. At relatively low temperatures, radiation-induced upgrading stays inactive without any contribution to the viscosity reduction process. However, as the temperature exceeds a specific threshold, radiation-induced chain reactions become activated, decreasing the viscosity of irradiated samples. At the end, we have investigated the effect of different additives upon radiolysis of hydrocarbon molecules. Interestingly, radiolytic reactions were completely suppressed by some of these additives.
