A method for conditioning of liquid fuels

The present invention relates to a method for conditioning liquid fuels, comprising the steps of: a) providing a liquid fuel, b) introducing at least one low boiling substance in the liquid fuel at a temperature of -75 ° C to + 75 ° C and a pressure of 1 bar to 1000 bar and thereby c) obtaining a conditioned liquid fuel. Further, the present invention relates to a conditioned liquid fuel comprising under standard conditions - 85 vol .-% to 99.99 vol .-% of a liquid fuel, and - 0,01 vol .-% to 15 vol .-% of at least one low-boiling substance. Finally, the use is described of a low boiling substance at least for improving the combustion of liquid fuels, or for conditioning of liquid hydrocarbons or hydrocarbon mixtures.
