The invention relates to petrochemistry, in particular to the production of petroleum distillate fractions. The goal is to increase the yield of distillate fractions. The oil is pre-ozonated at 20-80 ° C in a straight-flow vertical reactor with dispersion of liquid in the ozone-air mixture stream at an ozone flow rate of 10-50 g / kg of raw oil, then the gas phase is separated by separation and the oil is distilled. Distillation is carried out at atmospheric pressure with the selection of light distillates and fuel oil, further distillation of fuel oil in vacuum with the withdrawal of bulk distillates and the residue - tar, table 2. |
