Overview
Kerosene is a hydrocarbon liquid derived from petroleum distillation, typically obtained between 150°C and 275°C. It serves as an important energy source and industrial raw material with wide applications across multiple sectors. The composition varies depending on its source and intended use, generally containing 6-16 carbon atoms per molecule. In industrial contexts, kerosene is valued for its relatively high flash point compared to gasoline, making it safer to handle while still being easy to ignite when needed. The aviation industry heavily depends on specially refined kerosene (Jet A, Jet A-1) as the primary fuel for turbine-powered aircraft.
Physical and Chemical Properties
Kerosene exhibits several key physical properties that determine its applications. It has a density slightly lower than water (0.78-0.81 g/cm³) and a boiling range between 175°C and 325°C. The flash point ranges from 38°C to 72°C depending on the specific formulation, which is higher than gasoline but lower than diesel fuel. Chemically, kerosene consists of a mixture of aliphatic and aromatic hydrocarbons with carbon numbers predominantly in the C9-C16 range. It has a relatively low viscosity (1-2.5 mm²/s at 40°C) and good thermal stability, making it suitable for applications requiring clean combustion. The sulfur content varies significantly between grades, with aviation kerosene having the strictest purity requirements.
Main Applications
The primary use of kerosene is as aviation turbine fuel (Jet A, Jet A-1), accounting for the majority of global production. This specialized form undergoes rigorous refining to meet strict international standards for freezing point, flash point, and thermal stability. Other significant applications include heating fuel for portable and stationary heaters, particularly in areas without natural gas infrastructure. Kerosene serves as the fuel for traditional lamps (especially in developing regions), as a solvent in pesticide formulations, and in certain industrial processes requiring a clean-burning hydrocarbon liquid. Some niche uses include rust prevention, parts cleaning, and as a carrier for certain chemical applications.
Safety and Storage
As a flammable liquid, kerosene requires careful handling and storage. It should be kept in approved containers away from heat sources, sparks, and open flames. Storage areas must be well-ventilated to prevent vapor accumulation, which can create explosive mixtures with air. Personnel handling kerosene should use appropriate PPE, including gloves and eye protection. While not acutely toxic, prolonged skin contact can cause irritation and dermatitis. Spills should be contained using absorbent materials (never water) and disposed of according to local regulations. For large-scale storage, secondary containment systems are recommended to prevent environmental contamination.
B2B Procurement Guide
Industrial buyers should clearly specify the required kerosene grade (aviation, lamp, or industrial) and key parameters such as sulfur content, flash point, and freezing point when placing orders. Aviation-grade commands premium pricing due to its stringent refining requirements. Bulk purchases typically offer significant cost savings, with transportation logistics being a major consideration due to kerosene's classification as a hazardous material. Establish relationships with reputable suppliers who can provide consistent quality and proper documentation, including safety data sheets and certificates of analysis. Consider regional availability and seasonal demand fluctuations when planning procurement strategies.
