AVIATION GAS TURBINE FUEL WITH IMPROVED LOW TEMPERATURE OPERABILITY

The addition of biodiesel to petroleum-based kerosene jet fuels in very low concentrations can lower the temperature at which crystals appear in the fuel. The fuels can comprise a blend of a hydrocarbon base fuel component and, for example, up to 1000 ppm, v/v of the total fuel, of a biodiesel compo...

Beschreibung
Zusammenfassung:	The addition of biodiesel to petroleum-based kerosene jet fuels in very low concentrations can lower the temperature at which crystals appear in the fuel. The fuels can comprise a blend of a hydrocarbon base fuel component and, for example, up to 1000 ppm, v/v of the total fuel, of a biodiesel component comprising a lower alkyl ester of a fatty acid of natural origin having from 8 to 24 carbon atoms; these blends can be characterized by improved low temperature flow properties, especially of Cloud Point (ASTM D 2500), which can be lower than that of the petroleum fuel component without the alkyl ester, even in the presence of dissolved water up to the saturation level.
