METHODS FOR PROVIDING HIGHER QUALITY OF KEROSENE-BASED LIQUID FUELS FOR ENGINES Russian patent published in 2020 - IPC C10L1/04 

FIELD: fuel industry.

SUBSTANCE: invention discloses a method of producing liquid propellant fuels suitable as rocket propellants of RP-1 or RP-2 grades, involving: providing the presence of a hydrocarbon kerosene component with a boiling point in range of 145 °C to 300 °C at atmospheric pressure, a flash point of at least 60 °C or higher, measured in accordance with ASTM D56, and density at 15 °C, of not more than 815 kg/m³; providing a certain amount of a mixing component, which is a synthetic cycloparaffin kerosene fuel, containing at least 99.5 wt % carbon and hydrogen and at least 50 wt % cycloparaffins, wherein said mixing component, which is a cycloparaffin kerosene fuel, has a boiling point of not more than 300 °C at atmospheric pressure, a flash point, at least 38 °C, preferably at least 45 °C, preferably at least 50 °C, more preferably at least 55 °C, more preferably at least 60 °C, density at 15 °C, of at least 799 kg/m³, and the freezing point component of −60 °C or below, and said synthetic cycloparaffin kerosene fuel produced from biomass; and mixing a certain amount of mixing component, which is a synthetic cycloparaffin kerosene fuel, and a hydrocarbon kerosene component in amount, of at least 1 vol %, providing a flash point of at least 60 °C and a boiling point of 274 °C or lower to obtain mixed liquid propellant.

EFFECT: obtaining fuel of higher quality for reduction of harmful emissions into atmosphere.
