Jet fuel requires a specific molecular weight to keep plane engines from freezing
While cars run on gasoline, jet engines require a precise molecular recipe of hydrocarbons to ensure fuel remains liquid and functional in the freezing temperatures of high-altitude flight.
Jet fuel is a specialized form of kerosene composed of hydrocarbons within the C8 to C16 molecular weight range. This specific chemical structure is vital because commercial aircraft cruise at altitudes where outside temperatures can drop below minus forty degrees Fahrenheit. If the molecular weight is too high, the fuel can wax or freeze, clogging the engine's fuel lines.
