The influence of mechanical treatment (MT) on the composition, properties and transformations of crude oil devoid of gasoline fractions boiling up to 200°C and petroleum residua > 350°C (mazouts) was studied. It was established that the impact of mechanical energy upon crude oil in the presence of quartz particles almost halves the concentration of n -alkanes in the raw material and leads to formation of lowboiling fractions, hydrogen and hydrocarbon gases. The possibility of producing gasoline and diesel distillates from degasolined oil by means of its mechanochemical treatment is shown. The yields of these distillates increase when the stock is treated in the presence of quartz particles. The degree of destruction of mazouts rises if the raw material was ozonizated, then mixed with 5% of tetraline (H-donor), and finally subjected to mechanical treatment. It was shown that transformations of both coal and mazout components occur during mechanical treatment of mazout/coal mixtures.
