This article presents the results of the influence of ultrasonic exposure (UE) on the process of thermochemical destruction of fuel oil in the presence of shale of Kenderlyk field at different pressure intervals (3.5-5.5 MPa). A number of experiments were performed before and after ultrasonic exposure to select the working pressure for thermochemical processing of shale and fuel oil. Analysis of the results of pressure influence on the yield of thermochemical processing products shows that with increasing process pressure there is an increase of yield of gas, gasoline fraction (up to 180°C) and diesel fractions (180-360 °C) reaching maximum values in the range of 5.0 MPa. The yield of fractions that boil off at temperatures more than 360 °C are decreased with increasing pressure in the range of 3.5-5.5 MPa, and then begins to grow sharply with increasing pressure. After ultrasonic exposure at a temperature of 80 °C, a frequency of 22 kHz and 25 minutes of soaking the total yield of light distillates increases to 65.0 mass%. This is 10 units higher than without the use of UE. References [1] Elpiner I.E. Biophysics of ultrasound. М.: Science, 1973. 384 p. (in Russ.). [2] Kikuchi E. Ultrasonic Transducers.
