Introduction to Jet Fuel No. 3

No. 3 aviation kerosene is a transparent liquid blended from straight-run fractions, hydrotreated cracking fractions, hydrotreated fractions, and necessary additives. It is primarily composed of hydrocarbon compounds from different fractions. No. 3 aviation kerosene has an appropriate density, high calorific value, and excellent combustion properties, capable of burning rapidly, stably, continuously, and completely with a small combustion area, minimal carbon accumulation, and resistance to coking. It also maintains good low-temperature fluidity, meeting the requirements for oil flow in cold, low-temperature regions and high-altitude flights.

Aviation kerosene density

The ratio of the mass of aviation kerosene (excluding the pores of the kerosene) to the mass of an equal volume of water at a specific temperature (20℃). Generally measured using the density bottle method. The density of aviation kerosene is typically the relative density including minerals, which is related to the composition and content of the minerals present. The density increases with the increase in mineral content and also with the degree of alteration: the relative density of general aviation kerosene is usually less than 1.3, with some ranging from 1.3 to 1.4. Molecular formula: CH3(CH2)nCH3 (where n is 8 to 16).
