*****Expert Analyst Lin Mengjia*****crude oilWhat is the difference between diesel or gasoline? 

 Crude oil, also known as black gold, is commonly referred to as crude oil, which is extracted directly from oil wells without processing.

It is a black brown or dark green viscous liquid or semi-solid combustible substance composed of various hydrocarbons, and petroleum is stored in some areas of the upper crust. 

 Crude oil is composed of a mixture of different hydrocarbons, with the main component being alkanes. In addition, petroleum also contains elements such as sulfur, oxygen, nitrogen, phosphorus, and vanadium. According to its density range, it can be divided into light crude oil, medium crude oil, and heavy crude oil.(The oil composition and appearance of different oil fields can also vary greatly) 

 Crude oil, also known as heavy oil, cannot be directly used because it contains impurities. It needs to be refined and separated from useful impurities before it can be used. 

 Diesel is a light petroleum product with complex hydrocarbons(The number of carbon atoms is approximately10~22)Mix. Fuel for diesel engines. It is mainly composed of diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking;It can also be obtained through shale oil processing and coal liquefaction. 

 Gasoline is made from petroleum fraction or heavy fraction cracking, and processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and catalytic reforming all produce gasoline components. But straight run gasoline directly produced from crude oil distillation units is not used as engine fuel alone, but is refined, blended, and sometimes added with additives(Like the antiknock agent tetraethyl lead)To produce commercial gasoline. 

 Compared to gasoline, diesel contains more impurities and is more prone to producing smoke and dust during combustion, causing air pollution. Diesel does not produce toxic gases, making it more environmentally friendly and healthy than gasoline. 

 Gasoline and diesel are crude oil refining products, together with aviation kerosene, commonly known as finished oil. Gasoline, kerosene, and diesel are products distilled from crude oil at different temperatures, increasing in order of distillation temperature.
