Kerosene itself is actually a mixture of petroleum-based hydrocarbons and other compounds
Therefore, the precise freezing point of kerosene fuel varies
But regardless, it takes cooler temperatures for kerosene to freeze than it does for gasoline to freeze
In addition to a lower freezing point, kerosene has a higher flash point than gasoline
Refined from crude oil through a process known as fractional distillation, jet fuel is fundamentally a more refined version of kerosene
There are also different types of jet fuel that have many differences – from boiling point to octane rating to lower freezing point to aromatics, these types of aviation fuel are nuanced in many ways
Today, kerosene is mainly used in fuel for jet engines in several grades
One highly refined form of the fuel is known as RP-1, and is often burned with liquid oxygen as rocket fuel
These fuel grade kerosenes meet specifications for smoke points and freeze points
