Why do planes use kerosene?

Why do planes use kerosene? Can’t we use other types of fuel? Are there any requirements or anything else? Share our opinions and chat
Is the plane using kerosene for safety reasons?
Kerosene combines the high calorific value of diesel with the light weight of gasoline. Moreover, aviation fuel has extremely strict requirements regarding water content; in addition to the aforementioned requirements, aviation fuel also needs to have a low freezing point, as well as very strict limits on ash content and oxidizing properties.
Could you provide some specific information? I want to study hard!*

There are two types of fuel used in aircraft: aviation gasoline for spark-ignition piston engines, and jet fuel (commonly known as aviation kerosene) for gas turbine engines. So the standard term for that “kerosene” is “jet fuel”. There are both military and civilian applications; it depends mainly on the cost of use and specific technical requirements. Using “jet fuel” as the keyword, there is an abundance of information available online. China has a total of 6 types of jet fuel, and there is plenty of information available regarding jet fuel type 3. . The standards for many military and commercial jet fuels in the United States are public; you can even find information on the fuel used in the U.S. Army’s Tomahawk cruise missiles: lol
Thank you. Is aviation kerosene derived from coal tar? Can it be refined from coal tar?
After hydrogenation of coal tar, certain fractions of the product meet the specifications for aviation fuel. It can also be obtained from coal liquefied oil.
China’s coal tar production amounts to only 17 million tons per year, while the annual demand for aviation fuel is around 20 million tons, and this figure continues to rise (due to the increasing number of flight routes and the ongoing development of China’s air force). Therefore, technologies such as coal tar hydrogenation are suitable as a technical backup, but they cannot become the mainstream solution; after all, not all of the coal tar can be used for this purpose. The Fushun Petroleum and Chemical Research Institute seems to hold patents. Technology is often secondary; market segmentation for aviation fuel is what’s more important. Won’t those few barrels of oil still manage to divide up the market? ?
Hydrogenating coal tar to produce aviation fuel represents a technological extension and a supplementary source; it cannot become the mainstream. As you said, jet fuel depends on market segmentation and access rules
If you tell him to use 93 octane gasoline, it simply won’t be able to get moving

Some small training aircraft still use gasoline, although the octane rating of this gasoline is slightly higher. Before jet engines appeared, airplanes already used gasoline.
