On the night of 31 July 1853, doctors at the local hospital needed to perform an emergency operation, virtually impossible by candlelight. They therefore sent a messenger for Łukasiewicz and his new lamps. The lamp burned so brightly and cleanly that the hospital officials ordered several lamps plus a large supply of fuel. Łukasiewicz realized
737-540: A major political and environmental consequence. The Indian government subsidizes the fuel to keep the price very low, to around 15 U.S. cents per liter as of February 2007, as lower prices discourage dismantling of forests for cooking fuel. In Nigeria an attempt by the government to remove a fuel subsidy that includes kerosene met with strong opposition. Kerosene is used as a fuel in portable stoves , especially in Primus stoves invented in 1892. Portable kerosene stoves earn

As such, increase in the price of kerosene can have
871-805: A naturally occurring asphaltum called albertite . He was blocked from using it by the New Brunswick coal conglomerate because they had coal extraction rights for the province, and he lost a court case when their experts claimed albertite was a form of coal. In 1854, Gesner moved to Newtown Creek , Long Island , New York . There, he secured backing from a group of businessmen. They formed the North American Gas Light Company, to which he assigned his patents. Despite clear priority of discovery, Gesner did not obtain his first kerosene patent until 1854, two years after James Young 's United States patent. Gesner's method of purifying
938-418: A number of useful liquids from it, one of which he named paraffine oil because at low temperatures, it congealed into a substance that resembled paraffin wax. Young took out a patent on his process and the resulting products in 1850, and built the first truly commercial oil-works in the world at Bathgate in 1851, using oil extracted from locally mined torbanite, shale, and bituminous coal. In 1852, he took out
1005-505: A public demonstration in Charlottetown , Prince Edward Island of a new process he had discovered. He heated coal in a retort , and distilled from it a clear, thin fluid that he showed made an excellent lamp fuel. He coined the name "kerosene" for his fuel, a contraction of keroselaion , meaning wax-oil . The cost of extracting kerosene from coal was high. Gesner recalled from his extensive knowledge of New Brunswick 's geology
1072-438: A reputation of reliable and durable stove in everyday use, and perform especially well under adverse conditions. In outdoor activities and mountaineering, a decisive advantage of pressurized kerosene stoves over gas cartridge stoves is their particularly high thermal output and their ability to operate at very low temperature in winter or at high altitude. Wick stoves like Perfection's or wickless like Boss continue to be used by
1139-436: A result, the illuminating oil industry in the United States completely switched over to petroleum in the 1860s. The petroleum-based illuminating oil was widely sold as Kerosene, and the trade name soon lost its proprietary status, and became the lower-case generic product "kerosene". Because Gesner's original Kerosene had been also known as "coal oil", generic kerosene from petroleum was commonly called "coal oil" in some parts of
1206-405: A situation in which a romantic relationship has ended, but where one partner still loves the other. It is considered by some to be dated, but still in wide usage. A torch song is typically a sentimental love song in which a singer laments an unrequited love. Kerosene Kerosene , or paraffin , is a combustible hydrocarbon liquid which is derived from petroleum .

The transit agency started using this fuel in 2004, prior to the widespread adoption of ultra-low-sulfur diesel , which has since become the standard. In 2008, the suppliers of the custom fuel failed to tender for a renewal of the transit agency's contract, leading to a negotiated contract at a significantly increased cost. JP-8 (for "Jet Propellant 8"),
1407-422: Is a type of illuminated procession which is held after dark so that torches carried by the participants form a spectacle (other types of an illuminated procession involve candles, lanterns etc). Magnesium torches were used commonly in the 1950s and 1960s as a means of underwater illumination. Magnesium burns with a bright white light, and burns underwater also. The association of a torch with love may date to

#17327756510551474-551: Is also used to refer to a number of distinct petroleum byproducts other than kerosene. For instance, liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from petroleum. To prevent confusion between kerosene and the much more flammable and volatile gasoline (petrol) , some jurisdictions regulate markings or colourings for containers used to store or dispense kerosene. For example, in
1541-454: Is associated with higher risks of cancer , respiratory infections, asthma , tuberculosis , cataracts , and adverse pregnancy outcomes. Kerosene is a low- viscosity , clear liquid formed from hydrocarbons obtained from the fractional distillation of petroleum between 150 and 275 °C (300 and 525 °F), resulting in a mixture with a density of 0.78–0.81 g/cm . It is miscible with petroleum solvents but immiscible with water. It

Kerosene is used as a diluent in the PUREX extraction process, but it is increasingly being supplanted by dodecane and other artificial hydrocarbons such as TPH (Hydrogenated Propylene Trimer). Traditionally the UK plants at Sellafield used aromatic kerosene to reduce
1675-644: Is composed of hydrocarbon molecules that typically contain between 6-20 carbon atoms per molecule , predominantly containing 9 to 16 carbon atoms. Regardless of crude oil source or processing history, kerosene's major components are branched- and straight-chain alkanes (hydrocarbon chains) and naphthenes (cycloalkanes), which normally account for at least 70% of volume. Aromatic hydrocarbons such as alkylbenzenes (single ring) and alkylnaphthalenes (double ring), do not normally exceed 25% by volume of kerosene streams. Olefins are usually not present at more than 5% by volume. The heat of combustion of kerosene

The freezing point of kerosene depends on grade, with commercial aviation fuel standardized at −47 °C (−53 °F). Grade 1-K kerosene freezes around −40 °C (−40 °F, 233 K). The process of distilling crude oil/petroleum into kerosene, as well as other hydrocarbon compounds,
1876-424: Is produced by fractional distillation of crude oil in an oil refinery . It condenses at a temperature intermediate between diesel fuel , which is less volatile, and naphtha and gasoline , which are more volatile. Kerosene made up 8.5 percent by volume of petroleum refinery output in 2021 in the United States, of which nearly all was kerosene-type jet fuel (8.4 percent). The fuel, also known as heating oil in
1943-416: Is similar to that of diesel fuel ; its lower heating value is 43.1 MJ / kg (around 18,500 Btu / lb ), and its higher heating value is 46.2 MJ/kg (19,900 Btu/lb). The ASTM recognizes two grades of kerosene: 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). Grade 1-K kerosene burns cleaner with fewer deposits, fewer toxins, and less frequent maintenance than 2-K, and
2010-412: Is the preferred grade for indoor heaters and stoves. In the United Kingdom, two grades of heating oil are defined. BS 2869 Class C1 is the lightest grade used for lanterns, camping stoves, and wick heaters, and mixed with petrol in some vintage combustion engines as a substitute for tractor vaporizing oil . BS 2869 Class C2 is a heavier distillate, which is used as domestic heating oil. Premium kerosene
2077-420: Is used less for cooking, with LPG being preferred because it is easier to light. Kerosene is often the fuel of choice for range cookers such as Rayburn . Additives such as RangeKlene can be put into kerosene to ensure that it burns cleaner and produces less soot when used in range cookers. The Amish , who generally abstain from the use of electricity, rely on kerosene for lighting at night. More ubiquitous in

2144-498: Is usually sold in 5- or 20-litre containers from hardware, camping and garden stores, and is often dyed purple. Standard kerosene is usually dispensed in bulk by a tanker and is undyed. National and international standards define the properties of several grades of kerosene used for jet fuel . Flash point and freezing point properties are particularly interesting for operation and safety; the standards also define additives for control of static electricity and other purposes. Kerosene
2211-846: The Grandfather of the American Oil Industry by historians. Kier's salt wells began to be fouled with petroleum in the 1840s. At first, Kier simply dumped the oil into the nearby Pennsylvania Main Line Canal as useless waste, but later he began experimenting with several distillates of the crude oil, along with a chemist from eastern Pennsylvania. Ignacy Łukasiewicz , a Polish pharmacist residing in Lviv , and his partner Jan Zeh [ pl ] had been experimenting with different distillation techniques, trying to improve on Gesner's kerosene process, but using oil from

2479-533: The Chrysler Horizon that integrated many Saab components) were made. One reason to manufacture kerosene-fueled cars was that in Finland kerosene was less heavily taxed than gasoline. Kerosene is used to fuel smaller-horsepower outboard motors built by Yamaha, Suzuki, and Tohatsu. Primarily used on small fishing craft, these are dual-fuel engines that start on gasoline and then transition to kerosene once
2546-498: The Downer Company (to which Gesner had granted the right) were allowed to call their lamp oil "Kerosene" in the United States. In 1848, Scottish chemist James Young experimented with oil discovered seeping in a coal mine as a source of lubricating oil and illuminating fuel. When the seep became exhausted, he experimented with the dry distillation of coal, especially the resinous "boghead coal" ( torbanite ). He extracted

Such a torch is associated with the Greek god of marriage Hymen . The idiom to carry a torch (for someone) means to love or to be romantically infatuated with someone, especially when such feelings are not reciprocated . It is often used to characterize
2680-432: The UK and Ireland, remains widely used in kerosene lamps and lanterns in the developing world. Although it replaced whale oil , the 1873 edition of Elements of Chemistry said, "The vapor of this substance [kerosene] mixed with air is as explosive as gunpowder." This statement may have been due to the common practice of adulterating kerosene with cheaper but more volatile hydrocarbon mixtures, such as naphtha . Kerosene

Most of these uses of kerosene created thick black smoke because of the low temperature of combustion. A notable exception, discovered in the early 19th century, is the use of a gas mantle mounted above the wick on a kerosene lamp. Looking like a delicate woven bag above
3216-562: The distillation products appears to have been superior to Young's, resulting in a cleaner and better-smelling fuel. Manufacture of kerosene under the Gesner patents began in New York in 1854 and later in Boston —being distilled from bituminous coal and oil shale . Gesner registered the word "Kerosene" as a trademark in 1854, and for several years, only the North American Gas Light Company and
3283-521: The end of the 1970s, a working prototype was produced based on the Saab 99 GL. The car was designed to run on two fuels. Gasoline was used for cold starts and when extra power was needed, but normally it ran on kerosene or turpentine. The idea was that the gasoline could be made from peat using the Fischer–Tropsch process . Between 1980 and 1984, 3,756 Saab 99 Petros and 2,385 Talbot Horizons (a version of

The Civil War cut into American whaling temporarily, but only 105 whaling ships returned to sea in 1866, the first full year of peace, and that number dwindled until only 39 American ships set out to hunt whales in 1876. Kerosene, made first from coal and oil shale, then from petroleum, had largely taken over whaling's lucrative market in lamp oil. Electric lighting started displacing kerosene as an illuminant in
3551-483: The heavier hydrocarbons that previously went into kerosene were incorporated into diesel fuel. Kerosene kept some market share by being increasingly used in stoves and portable heaters. A pilot project by ETH Zurich used solar power to produce kerosene from carbon dioxide and water in July 2022. The product can be used in existing aviation applications, and "can also be blended with fossil-derived kerosene." Kerosene

In Europe following the Second World War, automobiles were similarly modified to run on kerosene rather than gasoline, which they would have to import and pay heavy taxes on. Besides additional piping and the switch between fuels, the head gasket was replaced by a much thicker one to diminish
3685-482: The late 19th and early 20th centuries, kerosene space heaters were often built into kitchen ranges, and kept many farm and fishing families warm and dry through the winter. At one time, citrus growers used a smudge pot fueled by kerosene to create a pall of thick smoke over a grove in an effort to prevent freezing temperatures from damaging crops. " Salamanders " are kerosene space heaters used on construction sites to dry out building materials and to warm workers. Before

However, kerosene remained the predominant commercial end-use for petroleum refined in the United States until 1909, when it was exceeded by motor fuels. The rise of the gasoline-powered automobile in the early 20th century created a demand for the lighter hydrocarbon fractions, and refiners invented methods to increase their output of gasoline, while decreasing their output of kerosene. In addition, some of

Kerosene was also produced during the same period from oil shale and bitumen by heating the rock to extract the oil, which was then distilled. During the Chinese Ming Dynasty , the Chinese made use of kerosene through extracting and purifying petroleum and then converted it into lamp fuel. The Chinese made use of petroleum for lighting lamps and heating homes as early as 1500 BC. Although "coal oil"
