How diesel is formed?

Diesel is formed from the natural breakdown of organic materials, primarily from ancient marine organisms, over millions of years. This process occurs under high pressure and temperature deep within the Earth's crust, resulting in the formation of crude oil. Crude oil is then extracted and refined, with diesel obtained through distillation and further processing to meet specific fuel standards. The refining process separates hydrocarbons by their boiling points, with diesel typically falling in the middle range.
