It contains the international advanced pre-processing section, esterification process and distillation process, and it meets the European Union Standards.

The prodution steps are as follows:

1. Preprocessing section of bio-oil: when heated to 65-70°C, bio-oil is leached to remove impurities.

2. Drying section: bio-oil without impurities is dehydrated and dried.

3. First esterification reaction: adding bio-oil dehydrated to methanol including 3% sulfuric acid, first esterification reaction starts, and it will take 1.5—2.5 hours.

4. Second esterification reaction: this esterification reaction will take 9—12 hours.

5. Vacuum drying section: Second esterification reactants are dried with vacuum, removing moisture, reducing water content below 3%.

6. Distillation section: with vacuum state, second esterification reactants after vacuum drying section are heated to 220°C, biodiesel forms by steaming. Then cooling biodiesel to be liquid, the liquid biodiesel is just finished biodiesel.

7. Methanol fine-distillation: after biodiesel is isolated, the remaining methanol liquid is distilled to form methanol. Methanol cooled can be reused.

Bio-oil can be plant oil, animal oil or high acid-value waste oil.
