What is kerosene

What is Kerosene?

Kerosene is a refined petroleum product created through the fractional distillation of crude oil. It represents one of the middle-range hydrocarbon fractions, positioned between lighter gasoline and heavier diesel fuel in terms of boiling point and carbon chain length. The fuel is essential to modern industrial operations, transportation, and energy systems.

Chemical Composition and Properties

Kerosene consists primarily of hydrocarbons with 10-14 carbon atoms per molecule. This composition gives it specific physical and chemical properties: it is a colorless to pale yellow liquid with a distinctive odor. The fuel has a density of approximately 0.8 kg/L and a specific gravity between 0.775 and 0.840.

Production and Refining

Kerosene is produced in petroleum refineries through fractional distillation at temperatures between 150-300°C. During this process, crude oil is heated and separated into different products based on their boiling points. Kerosene typically represents about 10-15% of the crude oil processed at modern refineries. Additional refining steps improve its quality and reduce impurities.

Major Uses and Applications

Aviation fuel is the largest single use of kerosene, particularly Jet A-1 fuel used in commercial aircraft. Other significant applications include:

• Heating oil for residential and commercial building systems
• Industrial fuel for power generation and manufacturing
• Lighting fuel in regions with limited electrical infrastructure
• Solvent in various industrial and manufacturing processes
• Diesel blending in some regions to adjust fuel properties

Safety and Storage

Kerosene has a flashpoint of approximately 38-65°C, making it less volatile than gasoline but more volatile than diesel. It must be stored in proper containers away from heat and ignition sources. The fuel produces toxic fumes when burned in poorly ventilated spaces and should be handled according to established safety guidelines.

Global Market and Environmental Considerations

Approximately 120 million tons of kerosene are consumed globally each year. Environmental concerns regarding kerosene focus on carbon emissions from combustion and the broader impacts of petroleum extraction. The aviation industry is exploring sustainable aviation fuels (SAF) as alternatives to traditional kerosene.
