METHOD OF REMOVING OXYGEN FROM LIQUID FUEL Russian patent published in 2021 - IPC F02M27/08 B01D19/00 B01D53/22 B01J19/10 F23K5/08 F02C7/22 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for removing oxygen dissolved in liquid fuel in order to reduce coke formation and can be used in systems for supplying liquid fuel to the combustion chamber of aircraft engines. The method for removing oxygen from liquid fuel consists in the fact that liquid fuel is preliminarily exposed to ultrasound for a predetermined time to form cavitation bubbles in the fuel, and then the fuel is fed into the combustion chamber. The time of exposure to ultrasound is selected from the range of 0.1-1 s, frequency and amplitude of sound pressure of ultrasound is selected from given ratios, and radius of the cavitation bubble is chosen to be larger than free path of the most active radical in gas mixture of the bubble, which limits the chain process of oxidation of fuel vapor by oxygen in it. In the process of exposure to ultrasound, degree of solubility of oxygen in liquid fuel is controlled, and with a constant degree of solubility, fuel is additionally influenced by an electric field with a strength selected from a given condition.

EFFECT: decrease in the concentration of oxygen in the fuel by means of exposure to ultrasound while reducing harmful effect of ultrasound on fuel.
