【 摘 要 】

The object of research is a process of hydrocarbons isomerization and synthesis of oxygen-content organic compounds in the cavitation field. The disadvantage of this method is that the increase in the octane number by 2-5 units does not solve the problem of improving the quality of such straight-run gasoline. To increase the efficiency of cavitation in the article it is proposed to inject hydrogen peroxide in the flow of gasoline. It is known that hydrogen peroxide at dynamic cavitation decomposes into two hydroxyl radicals, which can interact with molecules of alkanes with formation of methanol. Methanol is one of the most common additives that are injected in the composition of low-grade gasoline to improve its quality indicators.A characteristic feature of the proposed process is that it is only in the cavitation field. Dynamic cavitation is proposed to create cavitation fields.During the passage of fuel through the reactor cavitation field there is partial destruction of linear hydrocarbons with formation of alkyl radicals and subsequent recombination of radicals. Due to this, there is isomerization of linear hydrocarbons. As a result, the octane number of gasoline after cavitation processing increases by 2-5 units.The study proved that the gasoline processed by cavitation method with hydrogen peroxide can be used for production internal combustion engines. It is shown that the experiment was able to increase the octane number of gasoline using research method by 14,8 points (from 74,9 to 88,7) and 12,7 using motor method by 12,7 points (from 72,2 to 84,9). Maximum octane number is achieved at a pressure of 19-20 MPa.
