Description

Comprehensive Introduction to Refinery Kerosene — Technical Analysis, Applications, and Aviation Fuel Significance

Kerosene is one of the most strategically important middle-distillate fractions derived from crude oil, primarily due to its critical role as the main feedstock for aviation turbine fuels (Jet Fuel / ATF).

While kerosene is widely used in heating, lighting, and industrial applications, its highest-value and most technically demanding application lies in the aviation industry, where it serves as the base material for producing jet fuels such as Jet A-1.

The product discussed in this article is kerosene produced by Persian Gulf Star Oil Company, located in Bandar Abbas. This refinery is recognized as the largest gas condensate refinery In the Middle East, and the quality of its products is evaluated according to international standards.

In the following sections, a comprehensive technical analysis of specifications, applications, advantages, quality parameters, and expert insights is presented, with a particular focus on its aviation fuel potential.

Chemical Nature and Definition of Kerosene

Kerosene is a mixture of paraffinic, naphthenic hydrocarbons and a small fraction of aromatics, typically within the carbon number range of C9 to C16. This petroleum fraction distills approximately between 150°C and 275°C, positioning it between gasoline and diesel fuel.

Key characteristics include:

✅ Higher flash point compared to gasoline
✅ Lower volatility and improved storage safety
✅ Clean combustion with reduced soot formation
✅ Compatibility with a wide range of combustion systems

These properties make kerosene not only a widely used fuel, but also an ideal intermediate stream for aviation fuel production.
