used as a rocket
fuel is a type of kerosene
similar to the sort burned in heaters and lamps. However, the rocket petroleum is highly refined, and is called RP-1 (Refined Petroleum). It is burned with liquid oxygen
(the oxidizer) to provide thrust.
RP-1 is a fuel in the first-stage boosters of the Delta and Atlas-Centaur rockets. It also powered the first stages of the Saturn 1B and Saturn V. RP-1 delivers a specific impulse considerably less than that of cryogenic fuels.
