Kerosene is mainly used for lighting and various blowtorches, gas lamps, gasifiers and kerosene stove fuel; It can also be used as a detergent for mechanical parts, a solvent for the rubber and pharmaceutical industries, and an ink thinner.

pyrolysis raw materials for organic chemicals; Process oil for glass ceramics industry, aluminum plate rolling, chemical heat treatment of metal workpiece surface, etc.

According to the use, it can be divided into aviation kerosene.

Power kerosene, lighting kerosene, etc.

The role of kerosene.

The main use of kerosene.

It is mainly used for lighting and fuel for various blowtorches, gas lamps, vaporizers and kerosene stoves; It can also be used as a detergent for mechanical parts, a solvent for rubber and pharmaceutical industries, an ink thinner, and a pyrolysis raw material for organic chemicals; Process oil for glass ceramics industry, aluminum plate rolling, chemical heat treatment of metal workpiece surface, etc. Some kerosene is also used to make thermometers. According to the application, it can be divided into thermal kerosene, lighting kerosene, etc.

Sister Feng knew about Jia Lian's secret marriage, so she pretended to be virtuous and took the second sister into the house. Please ask Jia Mu and others to agree. Jia Lian came back, and because he did a good job, Jia Yu rewarded another concubine.

Sister Feng borrowed the hand of her concubine to force Second Sister You to commit suicide by swallowing gold. Daiyu made peach blossom poems, and everyone discussed reopening the poetry club and changing the Begonia Club to the Peach Blossom Club. Shi Xiangyun filled in the willow wadding, and Daiyu invited the public to fill in the willow wadding.

Everyone flew a kite, wanting to let go of the bad luck, the Daiyu kite line was broken, and everyone flew the kite. The silly eldest sister picked up a sachet embroidered with a spring palace painting in the garden, and Mrs. Wang was furious and copied the Grand View Garden under the pinch of Wang Shanbao's family. Tanchun was sad and angry, thinking that raiding the house was a bad omen.

Later, because Wang Shanbao's family lifted her clothes, she was furious and slapped Wang Shanbao's family. Jiafu Mid-Autumn Festival night banquet, Jia's mother invited everyone to Tubi Villa to admire the moon, and everyone beat drums and ate wine. Daiyu saw that many people in Jia's mansion admired the moon, and Jia's mother sighed that there were few people, not as lively as back then, and she didn't feel nostalgic for the scene.

Xiangyun came to accompany her, the two came to the Cave Jingxi Pavilion to join the poem, Xiangyun Lianhantang crossed the crane shadow, Daiyu buried the soul of the poem in the cold moon, Xiangyun praised Daiyu's poems for novelty, Miaoyu heard and praised, and transcribed the poems of the two of them and ended it.

It is a class of light petroleum products. It is obtained from natural or artificial petroleum by fractionation or cracking. Kerosene alone. Generally refers to lighting kerosene. It is also known as kerosene and lamp oil for lamps, also known as fire oil, commonly known as foreign oil, and also known as fire water in Cantonese. <

It is also known as kerosene and lamp oil for lamps, also known as fire oil, commonly known as foreign oil, and also known as fire water in Cantonese.

Kerosene is miscible with petroleum-based solvents. The solubility to water is very small, and kerosene containing aromatic hydrocarbons has greater solubility to water than kerosene, an aliphatic hydrocarbon. Kerosene dissolves absolute ethanol.

Mixtures with alcohols stratify when water is present at low temperatures. Kerosene has different chemical compositions for different purposes. The physical and chemical properties of the same kerosene are also different due to different production methods and origins.

The quality of various types of kerosene decreases in turn: thermal kerosene, solvent kerosene, kerosene for lamps, fuel kerosene, and washing kerosene.

The composition of kerosene is separated from petroleum, mainly organic matter composed of hydrocarbons, which produce carbon dioxide and water when burned, but because the carbon content is usually very high, if the oxygen is not very sufficient, you can see the incomplete conversion of carbon to form black smoke, usually that is activated carbon. For example, for organic matter such as methane: (note that kerosene is usually absent from kerosene, here is an example).

When oxygen is sufficient: CH4 + 2O2 = CO2 + 2H2O

When oxygen is insufficient: CH4+O2=C+2H2O

Kerosene is a mixture, and kerosene for different purposes has different chemical compositions. Due to different varieties, it contains 28-48% alkanes, 20-50% aromatic hydrocarbons, 1-6% unsaturated hydrocarbons, and 17-44% cyclic hydrocarbons. The number of carbon atoms is 10-16.

In addition, there are small amounts of impurities such as sulfides (mercaptans), gums, etc.

The so-called product kerosene is made from a blend of refined straight-run kerosene or hydrocracked kerosene fractions.

Its main components are C10-C16 alkanes, and also contain a small amount of aromatic hydrocarbons, unsaturated hydrocarbons, cyclic hydrocarbons and other impurities.

1. Kerosene (lamp kerosene; kerosene ；kerosine mainly refers to a chemical substance and is a class of light petroleum products. It is obtained from natural or artificial petroleum by fractionation or cracking.

2. It is mainly used for lighting and various blowtorches, gas lamps, vaporizers and kerosene furnaces; It can also be used as a detergent for mechanical parts, a solvent for rubber and pharmaceutical industries, an ink thinner, and a pyrolysis raw material for organic chemicals; Process oil for glass ceramics industry, aluminum plate rolling, chemical heat treatment of metal workpiece surface, etc. Some kerosene is also used to make thermometers. According to the application, it can be divided into thermal kerosene, lighting kerosene, etc.

Coal tar is a black viscous liquid extracted from coal and is an important chemical raw material. According to the use of coal tar, it can be divided into the following categories:

First, the chemical industry. Coal tar is the raw material for many important chemicals, such as the production of various synthetic resins, waterproof materials, pigments, dyes, medicines, spices, fertilizers, etc. In addition, coal tar is often used as a carrier for catalysts for chemical reactions.

2. Gas, heat and energy. Coal tar produces coal gas during the coking process, which is further used for power generation and heating. In addition, coal tar itself can also be used as a raw material for the production of fuel oil, kerosene, gasoline and liquefied gas, and has a wide range of applications in energy production.

3. Building materials. Coal tar is an important material for making asphalt and waterproofing materials, and is used in the production of paving asphalt, roof asphalt and other building materials. In addition, coal tar can also be used in the production of sandwich glass fiber, reinforced concrete and other materials, and can also be used as a raw material for architectural coatings and preservatives.

In general, coal tar has important application value in the fields of industry, agriculture, medicine, construction and other fields. Through scientific and technological innovation and industrial transformation and upgrading, the application field of coal tar will be further expanded and expanded in the future. At the same time, in order to protect the environment and reduce energy consumption, the development of alternatives to coal tar is also attracting more and more attention.
