'''Kerosene''' is obtained from the fractional distillation of petroleum at 150°C and 275°C (carbon chains from the C12 to C15 range).

'''RP-1''' is a highly refined form of kerosene similar to jet fuel, used in the United States as a [[rocket fuel|rocket fuel]]. RP-1 is typically burned with LOX ([[liquid oxygen]]) as the oxidizer. Although having a lower specific impulse than [[liquid hydrogen]] and thus thrust per mass, RP-1 is cheaper, can be stored at room temperature, is far less of an explosive hazard and is far more dense (a given volume of RP-1 is significantly more powerful than a similar volume of LH2) and more practical for many uses.

RP-1 is the fuel in the first-stage boosters of the Delta and Atlas rockets. It also powered the first stages of the Titan I, Saturn IB and Saturn V.

Russian rocket-grade kerosene is of very similar standard as RP-1 and is designated T-1 and RG-1. Russian rocket grade kerosene is formulated for higher densities though (0.82 to 0.85 g/ml) compared to American RP-1 at 0.81 g/ml, and the Russians achieved even higher densities by super-chilling the kerosene in a rocket’s fuel tanks, but this partially defeats the purpose of using kerosene over other fuels.
