Brief introduction of biodiesel oil:
The biodiesel can be used as substitute product of petroleum fuel. It is can be produced by vegetable oil fat and animal fat, but at present, most people using the fatty acid, swill oil, used cooking oil and leftovers which produced in refining process as the materials.
The biodiesel not only can be used for biofuel, it also can be as diesel fuel additive. In recent 20 years, using the vegetable oil to make the biodiesel to instead the petroleum fuel, it already aroused more and more attentions from all over the world. At present, The European and North America countries utilizing the vegetable oil as biodiesel materials, but Japan through recycling used cooking oil to make biodiesel.
Advantaged, it also can be efficient utilized the waste, at the meanwhile, it can reduce the pollution of used cooking oil.
In nowadays, biodiesel is already widely applied as engin fuel in tractor, cars, and sedans.
The advantages of biodiesel oil:
1. Engine is starting at low temperature (-10°C)
2. It not belongs to dangerous cargo, so itâs easy to transport.
3. There is less sulfur and aromatic alkyl in biodiesel, so itâs less harmful to human and environment.
4. As a kind of renewable energy sources, the biodiesel will not finised.
5. The supply of biodiesel is not controlled by OPEC, itâs benefit to the stability of international petroleum market.
