Gasoline
| Gasoline | It is a volatile and flammable hydrocarbon mixture liquid distilled and cracked from petroleum, which can be used as a fuel. It appears as a transparent liquid and is flammable, with a distillation range of 30°C to 220°C. The main components of gasoline are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (resistance to knocking combustion), and it is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on its octane number. Starting from January 2012, the gasoline grades of 90, 93, and 97 were revised to 89, 92, and 95. |
| Uses | Gasoline is one of the most widely used light petroleum products and serves as an important fuel for engines. Based on the manufacturing process, gasoline components can be classified into straight-run gasoline, thermally cracked gasoline (coking gasoline), catalytically cracked gasoline, catalytically reformed gasoline, polymerized gasoline, hydrocracked gasoline, alkylated gasoline, and synthetic gasoline, among others. Gasoline is primarily used as a power fuel for transportation vehicles. In industries such as rubber, paint, dye, printing, pharmaceuticals, and adhesives, gasoline is used as a solvent. It is also used as a degreaser for cleaning machine parts, clothing, and for pretreatment of electroplated products to remove oil. |
Diesel oil
| Diesel oil | It is a light petroleum product, a mixture of complex hydrocarbons (with about 10-22 carbon atoms), used as diesel fuel. It is mainly composed of diesel fractions produced by processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced by shale oil processing and coal liquefaction, and is divided into two categories: light diesel (boiling point range of about 180-370 ℃) and heavy diesel (boiling point range of about 350-410 ℃). Widely used in large vehicles, railway locomotives, and ships. |
| Uses | The most significant use of diesel is as a fuel for diesel engines in vehicles and ships. It is also used as a power source for tractors, large trucks, diesel locomotives, as well as construction machinery such as excavators, loaders, fishing boats, diesel generators, and agricultural machinery. It serves as the fuel for diesel-powered vehicles like diesel cars and tractors. Compared to gasoline engines, diesel engines offer higher thermal efficiency and lower fuel consumption rates. Due to diesel's low energy consumption, some small cars and even high-performance vehicles have switched to using diesel. |
Fuel oil
| Fuel oil | In Europe, the term "fuel oil" generally refers to the black, viscous residue left after crude oil distillation, or a blend of this residue with lighter components. It is primarily used as a fuel for steam boilers and various heating furnaces, or as a fuel for large, slow-speed diesel engines, as well as for various industrial applications. However, in the United States, the term refers to any combustible liquid or liquefiable petroleum product with a flash point of not less than 37.8°C. This can be either Residual Fuel Oil (also known as Heavy Fuel Oil) or Heating Oil. Heating Oil can be obtained directly from crude oil distillation (i.e., straight-run distillate) or through distillation of other processed products, such as those from cracking processes. |
| Uses | In the power industry, fuel oil consumption is mainly used for oil-fired power generation, heating in heating units, and for ignition, combustion support, and flame stabilization in coal-fired units. In the steel industry, fuel oil is primarily used in heating furnaces, power generation and heating in self-contained power plants, and in refractory materials. In the building materials industry, fuel oil consumption is mainly used in the production of flat glass and architectural and sanitary ceramics. As product quality requirements increase, some high-end production processes will gradually shift towards using natural gas and liquefied petroleum gas as fuels. In the petrochemical industry, fuel oil is used mainly for power generation in self-contained power plants, heating in oilfield living quarters, process heating in refinery operations, raw materials and fuel in fertilizer plants, and other chemical production processes. |
