FIELD: chemistry.
SUBSTANCE: invention relates to the application of, at least, one alcohol (C6-C15)ethoxylate and, at least, one (C8-C24)alkylamido (C1-C6)alkylbetaine in liquid hydrocarbon fuel, which contains less than 50 ppm of water, to reduce or essensially eliminate the formation of ice particles with the weight average particle size larger than 1 mcm, in the said liquid hydrocarbon fuel, when the said liquid hydrocarbon fuel is cooled to temperatures, which are in the range from 0 to -50°C, where the quantity of the said, at least, one alcohol (C6-C15)ethoxylate in the said fuel constitutes from 45 to 4575 ppm by weight, and the quantity of the said, at least, one (C8-C24)alkylamido (C1-C6)alkylbetaine constitutes from 5 to 425 ppm by weight. Described is aviation fuel, which has lower tendency to ice particles formation. The invention also relates to a method of reducing or elimination of the formation of ice particles in the liquid hydrocarbon fuel. Also described is a method of an aircraft refuelling with the liquid hydrocarbon fuel, which has lower tendency to ice particle formation.
EFFECT: reduction or elimination of formation of ice plugs in fuel and fuel tanks of an aircraft with gas turbine engines.
