Diesel oil is a light petroleum product and a mixture of complex hydrocarbons (carbon atoms about 10 ~ 22). Fuel the diesel engine. It is mainly composed of diesel distillates produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking and petroleum coking; It can also be produced by shale oil processing and coal liquefaction. It can be divided into light diesel oil (boiling point range about 180 ~ 370 ℃) and heavy diesel oil (boiling point range about 350 ~ 410 ℃). It is widely used in large vehicles, railway locomotives and ships.
The fraction of liquid petroleum with a boiling point range and viscosity between kerosene and lubricating oil. Flammable, volatile, insoluble in water, soluble in alcohol and other organic solvents. It is a mixture of complex components, with boiling points ranging from 180 ℃ ~ 370 ℃ and 350 ℃ ~ 410 ℃.
The fraction of liquid petroleum with a boiling point range and viscosity between kerosene and lubricating oil.
The main indicators are cetane number, viscosity, freezing point, etc. The quality requirements of diesel oil are good combustion performance and fluidity. The higher the cetane number, the better the combustion performance. The cetane number of diesel oil made from Daqing crude oil can reach 68. The cetane number of light diesel used in high-speed diesel engine is 42 ∼ 55 and that at low speed is below 35.
