Abstract
The article presents the results of electromagnetic activation of petroleum raw materials in the vortex layer apparatus. It is shown that under electromagnetic influence, there is a significant increase in the proportion of straight-run gasoline fraction distillate, as well as a change in the physicochemical parameters of the light fractions obtained. It is established that the processes of wave action on oil, which take place in the zone of the electromagnetic field, lead to a change in the group hydrocarbon composition of the distillates obtained. NMR spectroscopy was used to study the effect of electromagnetic radiation on the properties of oil raw materials on the physicochemical properties and structure of the oil.
