Increasing the Yield of Light Distillates by Activation of Oil Stock

It is shown that activation of oil by a rotary pulsation acoustic device that generates acoustic vibration in a wide range of acoustic frequencies, depending on the intensity of acoustic impact, can help increase the yield of gasoline fraction up to 10 wt. % of its potential content in the original oil stock. The mechanisms of change in physicochemical properties, fractional composition, and quality parameters (density, refractive index, octane and cetane number, etc.) of gasoline and diesel fractions recovered by distillation of activated oil, depending on the conditions of acoustic impact, are ascertained. The studies demonstrated the feasibility of implementation of an alternative method of enhancing the yield of light distillates through activation of oil stock by acoustic impact.
