But this versatile hydrocarbon fuel does far more than that. From powering commercial aircraft at 35,000 feet to degreasing heavy machinery on the factory floor, kerosene remains one of the most widely used petroleum distillates on Earth. With approximately 1.4 million barrels consumed daily in the United States alone, kerosene is anything but outdated.

In this comprehensive guide, we explore every major application of kerosene, compare it to competing fuels, examine different grades, and provide essential storage and safety guidance. Whether you are a facility manager sourcing heating fuel, an industrial buyer evaluating solvents, or a homeowner preparing for winter, this article will give you the knowledge you need to use kerosene effectively and safely.

What Is Kerosene?

Kerosene (also called paraffin oil in some countries) is a flammable hydrocarbon liquid derived from the fractional distillation of crude petroleum. It sits between gasoline and diesel in the distillation column, typically consisting of hydrocarbons with 10 to 16 carbon atoms per molecule (C₁₀ to C₁₆). The name "kerosene" originates from the Greek word keros (wax), reflecting its early production from coal and oil shale.

First commercially produced by Canadian geologist Abraham Gesner in 1846, kerosene rapidly replaced whale oil as the dominant lamp fuel, helping save whale populations from over-hunting. By the 1860s, kerosene refineries had sprung up across North America and Europe. Today, kerosene is produced in enormous quantities as both a standalone product and a precursor to jet fuel.

Key Physical Properties

• Boiling range: 150 to 300 °C (302 to 572 °F)
• Flash point: 38 to 72 °C (100 to 162 °F), much higher than gasoline
• Energy density: approximately 135,000 BTU per gallon (43 MJ/kg)
• Specific gravity: 0.78 to 0.82
• Auto-ignition temperature: 220 °C (428 °F)
• Appearance: Clear to pale yellow liquid with a characteristic petroleum odor

These properties make kerosene safer to store and transport than gasoline while still delivering impressive energy output. Its relatively low volatility reduces explosion risk, and its high BTU content makes it economical for heating and power generation.

Kerosene Grades Comparison

Not all kerosene is the same. The grade you choose depends on your application, required purity, and regulatory requirements. Here is a detailed comparison of the most common grades:

Heating Fuel: K-1 Clean-Burning Kerosene

Kerosene remains one of the most reliable heating fuels available, particularly in regions where natural gas infrastructure is limited or during power outages when electric heating fails. According to the U.S. Energy Information Administration, approximately 500,000 American households still rely on kerosene for primary or backup heating.

Why Choose Kerosene for Heating?

• High energy density: At 135,000 BTU per gallon, kerosene delivers more heat per dollar than many alternatives
• Grid independence: Portable kerosene heaters require no electricity, making them invaluable during winter storms
• Rapid heat delivery: Modern wick and forced-air kerosene heaters can warm a room within minutes
• Extended storage life: Properly stored K-1 kerosene can last up to 5 years with stabilizer additives
• Portability: Units can be moved from room to room or used in workshops, garages, and construction sites

Types of Kerosene Heaters

Convective heaters use a circular wick and chimney to radiate heat in all directions, ideal for large open spaces. Radiant heaters direct heat in one direction using a reflector, perfect for spot-heating in workshops or garages. Forced-air heaters use a fan and fuel pump to produce intense heat for construction sites and warehouses.

Aviation Fuel: Jet A and JP-8

The single largest consumer of kerosene worldwide is the aviation industry. Jet A (commercial) and JP-8 (military) are highly refined kerosene formulations that meet stringent specifications set by ASTM International and the U.S. military. In 2024, global aviation consumed approximately 100 billion gallons of jet kerosene.

Why Kerosene Powers the Skies

• Freeze point: Jet A has a maximum freeze point of -40 °C (-40 °F), keeping fuel liquid at cruising altitude temperatures of -50 °C
• Energy per pound: At 18,400 BTU/lb, kerosene-based jet fuel offers optimal energy-to-weight ratio
• Thermal stability: Resists decomposition at high temperatures inside turbine engines
• Safety margin: Higher flash point than gasoline means reduced fire risk during fueling and maintenance

The push toward sustainable aviation fuel (SAF) involves blending bio-derived kerosene with conventional Jet A. These blends can reduce lifecycle carbon emissions by up to 80% while requiring no engine modifications. This aligns with the broader movement toward green chemistry practices across industries.

Solvent and Cleaning Applications

Beyond its role as a fuel, kerosene is a highly effective industrial solvent. Its ability to dissolve greases, oils, waxes, and tar makes it indispensable in maintenance departments and manufacturing facilities worldwide.

Common Cleaning Uses

• Engine degreasing: Dissolves built-up oil and grime on automotive and heavy equipment engines
• Parts washing: Used in parts washers to clean metal components before assembly or inspection

Metalworking and Cutting Fluid

In precision machining, kerosene serves as both a cutting fluid and a lubricant. Its low viscosity allows it to penetrate the tool-workpiece interface rapidly, carrying away heat and metal chips while preventing the tool from seizing.

Metalworking Applications

• Electrical discharge machining (EDM): Kerosene is the traditional dielectric fluid in wire and sinker EDM, providing electrical insulation while flushing debris
• Honing and lapping: Acts as a carrier for abrasive compounds during surface finishing operations
• Tapping and drilling: Reduces friction and extends tool life in manual and CNC machining of aluminum, brass, and steel
• Rust prevention: Thin kerosene film protects freshly machined surfaces from oxidation during storage

For automotive and industrial coatings that often follow machining operations, proper solvent selection matters. Learn how n-butyl acetate fits into the coating process in our article on n-butyl acetate for automotive coatings.

Agricultural Heating

Farmers and growers rely on kerosene heaters to protect crops, livestock, and stored goods from temperature extremes. The portability and high heat output of kerosene make it especially practical in rural areas without reliable utility connections.
