Black diesel, also called non-standard diesel, refers to the raw material oil after distillation, catalytic cracking, hydrogenation, because of the sulfur and aromatic hydrocarbon in the oil and air and light reaction and oxidation of black oil.

Diesel oil is a light petroleum product, a complex mixture of hydrocarbons (about 10 to 22 carbon atoms).

For diesel fuel.

Mainly by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes produced by diesel distillates blending;

It can also be made from shale oil processing and coal liquefaction.

Divided into light diesel oil (boiling point range of about 180 ~ 180 ℃) and heavy diesel oil (boiling point range of about 350 ~ 350 ℃) two kinds big.

Widely used in large vehicles, railway locomotives, ships.


The most important use of diesel fuel is diesel engines for vehicles and ships.

Compared with gasoline, diesel has high energy density and low fuel consumption rate.

Diesel is low in energy consumption, so some small cars and even high-performance cars have switched to diesel.
