What is the composition of jet fuel?


Molecular weight: ≈185
Composition: C9–C16 paraffins, vol % ≈ 53%; cycloparaffins, vol % ≈ 31%; aromatics, vol % ≈ 16%; olefins, vol % ≈ 0.5%. Aromatics typical of cracked gasoline and kerosene include benzene, alkyl benzenes, toluene, xylene, indenes, naphthalenes. Benzene content = 0.02%.

How much does jet fuel expand?

A typical value for the coefficient of thermal expansion of kerosine-type jet fuel is 0.00099 per degree Celsius [(°C)–1] [(0.00055°F)–1]. At this rate, one gallon of jet fuel will expand 4.0 percent for an increase in temperature of 40°C [1.000 gallon at 0°C (32°F): 1.040 gallon at 40°C (104°F)].

What is the difference between Jet A and Jet A1?

Jet A is used in the United States while most of the rest of the world uses Jet A-1. The important difference between the two fuels is that Jet A-1 has a lower maximum freezing point than Jet A (Jet A: –40°C, Jet A-1: –47°C). Many years of experience have shown that Jet A is suitable for use in the United States.

What is the IS specification for Jet A-1 fuel?

Jet A-1. Jet A-1 is a kerosine grade of fuel suitable for most turbine engined aircraft. It has a flash point minimum of 38 degrees C (100°F) and a freeze point maximum of -47 degrees C.

Is Jet A kerosene?

Jet fuel (Jet A-1 type aviation fuel, also called JP-1A) is used globally in the turbine engines (jet engines, turboprops) in civil aviation. This is a carefully refined, light petroleum. The fuel type is kerosene. There are also additives that prevent the growth of organisms in aviation fuel.

Can I use jet fuel in my car?

Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Both are derived from crude oil, and both run their respective engines on combustion.

What fuel do jet engines use?

Aviation kerosene
Aviation kerosene is the fuel of choice for aircraft across the globe.

What is the classification of jet fuel?

Jet fuels are sometimes classified as kerosene or naphtha-type. Kerosene-type fuels include Jet A, Jet A-1, JP-5 and JP-8. Naphtha -type jet fuels, sometimes referred to as “wide-cut” jet fuel, include Jet B and JP-4.

What is the chemical formula of jet fuel?

Jet fuel is a mixture of hydrocarbons (similar to gasoline) Hydrocarbons burn in oxygen (in the air) Hydrogen + Oxygen = Water (H2O) Carbon + Oxygen = Carbon dioxide (CO2) So when jet fuel is burnt, it makes water and carbon dioxide. Because you are adding lots of oxygen, the about of water produced is a bit bigger than the amount of fuel burnt.

What is the constituent of jet fuel?

Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound.

What are the specifications for jet fuel?

The basic civil jet fuel specification used in the United States of America is ASTM Specification for Aviation Turbine Fuels D 1655, which defines the requirements for three grades of fuel:- Jet A, a kerosine type fuel having a maximum freeze point of -40 degrees C.
