Distillation range aviation fuel

Jet fuel is kerosene-based aviation fuel. It is medium distillate used for aviation turbine power units and usually has the same distillation characteristics and flash point as kerosene. Jet fuels are manufactured predominately from straight-run kerosene or kerosene-naphtha blends in the case of wide cut fuels that are produced from the atmospheric distillation of crude oil. Jet fuels are similar in gross composition, with many of the differences in them attributable to additives designed to control some fuel parameters such as freeze and pour point characteristics. For example, the chromatogram (Figure 27.4) of a commercial jet fuel (Jet A) is dominated by GC-resolved n-alkanes in a narrow range of n-C-j to n-Cig with maximum being around n-Ci. The UCM is well dehned. 

Mid-range distillates are typically products in a relatively broader carbon range (Ce to C26) and include kerosene (a flammable pale yellow or colorless oily liquid with a characteristic odor intermediate in volatility between gasoline and diesel oil that distills between 125 and 260°C), aviation jet (turbine) fuels, and lighter diesel products. 

Kerosine, diesel, and aviation turbine fuel (jet fuel) are members of the class of petroleum products known as middle distillates. As the name implies, these products arc heavier than gasoline but lighter than gas oils. Middle distillates cover the boiling range from approximately 175 C to 375 C (3 SOT to 700T) and the carbon number range from about Cg to C24.
