Biodiesel is a combination of biomass energy and traditional fossil energy that can be partially regenerated.

And diesel is fossil energy, it can’t be regenerated, and it’s always useful.

First, biodiesel

It is prepared by using different unprocessed or used vegetable oils and animal fats through different chemical reactions.

It is an environmentally friendly biofuel. This biofuel can be used like diesel. The most common preparation method for biodiesel is transesterification. reaction. Triglycerides, which are the main constituents of vegetable oils and fats, react with alcohols (usually methanol) in the presence of a catalyst.

Form fatty acid esters. The physical and chemical properties of fatty acid esters are very similar or even better than diesel.

【Industry Status】

  1. Biodiesel is a clean renewable energy source. It uses oil crops such as soybeans and rapeseed, oil palm and yellow wood.

Liquid fuel made from raw materials such as oil and algae, such as microalgae, animal fats and waste cooking oil, is a high quality stone.

Oil and diesel substitutes. Biodiesel is a typical “green energy”, vigorously develop biodiesel for sustainable economic development, and promote energy .Source substitution, reducing environmental pressure and controlling urban air pollution have important strategic significance.

2, look at the international developed countries such as the United States, Germany, Japan; the next developed South Africa, Brazil, South Korea; and then to the development

India, Thailand, etc. are all developing international policy systems, technological improvements, plant construction and vehicle manufacturing in the oil substitution industry.

It provides a good reference and paves the way for China to take the road of oil substitution with Chinese characteristics. Especially the Brazilian experience is more practical.


[Application field]

  1. Biodiesel can be used as a fuel for boilers, turbines, diesel engines, etc. The main application in the industry is fatty acid methyl esters.
  2. Biodiesel is a kind of high quality clean diesel oil that can be extracted from various biomasses. Therefore, it can be said that it is inexhaustible and inexhaustible.

Energy, in the face of increasingly depleted resources, is expected to replace oil as an alternative fuel.

  1. Diesel is the main power fuel for many large vehicles such as trucks, diesel locomotives and generators. It has great power and the price is high.The advantage of China is that the demand for diesel is very large. The main problem of diesel application is “black smoke”. We often see it on the road.Black smoke truck.The main cause of black smoke is incomplete combustion and serious air pollution, such as the production of a large amount of particulate dust.High CO2 emissions.

Second, diesel It is a light petroleum product with a mixture of complex hydrocarbons (about 10 to 22 carbon atoms). For diesel fuel. Mainly distilled and reminded by crude oil

The diesel fraction produced by the processes of cracking, thermal cracking, hydrocracking, petroleum coking, etc.; or shale oil processing and coal Liquefaction preparation. Divided into light diesel (boiling range of about 180 ~ 370 ° C) and heavy diesel (boiling range of about 350 ~ 410 ° C) two categories. wide It is widely used in large vehicles, railway locomotives, and ships.

Two. Diesel

It is a light petroleum product, a mixture of complex hydrocarbons (about 10-22 carbon atoms). Fuel for diesel engines. It is mainly composed of diesel fractions produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking, etc. It can also be produced by shale oil processing and coal liquefaction. It can be divided into two categories: light diesel (boiling point range is about 180-370 degrees C) and heavy diesel (boiling point range is about 350-410 degrees C). It is widely used in large vehicles, railway locomotives and ships.


It is a diesel engine for vehicles and ships. Compared with gasoline, diesel fuel has higher energy density and lower fuel consumption, but more harmful components (NO, particulate matter, etc.) are contained in the exhaust gas.

[Domestic market]

The reduction of sulfur content will directly reduce the emission of pollutants by about 50%, improve the atmospheric environment, and have obvious environmental benefits. The reduction of sulphur content can reduce the corrosion and damage to the engine and the amount of sediment, make the engine cleaner and prolong the service life of the engine.
