Key Differences

Petroleum, sourced from beneath the earth's surface, is crude oil that is processed in refineries to separate useful components. Whereas kerosene, a specific fraction derived during the distillation of petroleum, is notable for its lower boiling point and specific uses.
In the refining process, petroleum is heated and its vapors are collected at different temperatures to yield various products, including gasoline, diesel, and kerosene. Kerosene, on the other hand, condenses at a temperature range of 150 to 275 degrees Celsius, highlighting its distinct characteristics.
Petroleum serves as a raw material for countless derivatives including plastics, solvents, and various types of fuels. Kerosene, however, is primarily used as a fuel for jet engines, heating, and in lamps, emphasizing its narrower scope of application.
The global market for petroleum is vastly larger, influencing world economics and politics due to its essential role in energy supply chains. Kerosene, while important, has a more limited impact and is focused on specific market segments such as aviation fuel and domestic heating.
Regarding environmental impact, the combustion of petroleum products emits pollutants and greenhouse gases. Kerosene, when burned, also releases harmful emissions, but its cleaner burning nature compared to heavier oils makes it a slightly better option in terms of air quality and soot production.

Used as a base for many chemical products.
Many cosmetics contain ingredients derived from petroleum.

Kerosene

A clear combustible oil distilled from petroleum, primarily used as fuel.
Kerosene lamps were once common in households.

Petroleum

Crude oil that comprises a complex blend of hydrocarbons.
The petroleum extracted from the oil field was sent to a refinery.

Kerosene

Used in jet engines and heating systems.
The airport stores large quantities of kerosene for refueling aircraft.

Petroleum

Heavily traded on global commodity markets.

Petroleum

Petroleum (), also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels.

Kerosene

Kerosene is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households.

Petroleum

A liquid mixture of hydrocarbons which is present in suitable rock strata and can be extracted and refined to produce fuels including petrol, paraffin, and diesel oil; oil.

Kerosene

A thin oil distilled from petroleum or shale oil, used as a fuel for heating and cooking, in lamps, and as a denaturant for alcohol. Also called coal oil.

Petroleum

A thick, flammable, yellow-to-black mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally beneath the earth's surface, can be separated into fractions including natural gas, gasoline, naphtha, kerosene, fuel and lubricating oils, paraffin wax, and asphalt and is used as raw material for a wide variety of derivative products.

Kerosene

A thin colorless to straw-colored petroleum-based fuel heavier than gasoline/petrol or naptha but lighter than diesel, used primarily as jet fuel but also for heating and lighting in some remote or impoverished areas.
The kerosene lasted all winter, so the furnace kept us always warm.

Petroleum

A flammable liquid ranging in color from clear to very dark brown and black, consisting mainly of hydrocarbons, occurring naturally in deposits under the Earth's surface.

Kerosene

An oil used for illuminating purposes, formerly obtained from the distillation of mineral wax, bituminous shale, etc., and hence called also coal oil. It is now produced in immense quantities, chiefly by the distillation and purification of petroleum. It consists chiefly of several hydrocarbons of the methane series, having from 10 to 16 carbon atoms in each molecule, and having a higher boiling point (175 - 325° C) than gasoline or the petroleum ethers, and a lower boling point than the oils.

Petroleum

Rock oil, mineral oil, or natural oil, a dark brown or greenish inflammable liquid, which, at certain points, exists in the upper strata of the earth, from whence it is pumped, or forced by pressure of the gas attending it. It consists of a complex mixture of various hydrocarbons, largely of the methane series, but may vary much in appearance, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc.

Petroleum

A dark oil consisting mainly of hydrocarbons

Common Curiosities

What are the economic implications of petroleum?

Petroleum plays a crucial role in the global economy, affecting everything from energy prices to geopolitical strategies.

Can kerosene be used in cars?

Kerosene is not typically used in cars; it is more commonly used in jet engines and heating systems.

How is kerosene made?

Kerosene is made by distilling petroleum at temperatures between 150 to 275 degrees Celsius.

Is kerosene safer to use than gasoline?

Yes, kerosene is generally safer to handle and store than gasoline due to its higher flash point.
