Abstract:
1. A method of processing paraffinic and aromatic oils comprising: providing a paraffinic oil mixture consisting of heavy oils, oxygen-containing gas introduced under pressure to maximize the surface-to-volume ratio of air to oil, contaminants found in the natural state of an oil deposit, additives which have an effect to prevent the radiation-induced free radicals present in an oil source from cross-linking, added surfactants and optionally titanium oxide; said heavy oils comprising paraffinic oils higher than 5.7%; irradiating said paraffinic oil mixture with an electron beam; providing a constant dose rate in an energy range of 0.05 to 0.5 MeV at a dose rate of 0.5-4 kGy/sec; in a temperature range of 50-250° C.; with introduction of an oxygen-containing gas prior to said irradiating; maintaining an oxygen concentration near its saturation level throughout the irradiation; and resulting thereby in a chain reaction for oxidative scission to obtain lower molecular weight fractions.
