Abstract
Description
Technical Field

[0002] Biodiesel is fatty acid methyl ester generated by the reaction of waste animal and vegetable oils and fats with methanol. It is a renewable, low-carbon and clean energy source that can replace traditional petroleum diesel. However, when no antioxidant is added, the oxidation stability of biodiesel is generally low, usually not exceeding 2 hours, which limits its stability and storage period in practical applications. To improve the oxidation stability of biodiesel, the method of adding antioxidants is generally adopted. Antioxidants can extend the storage period of biodiesel and improve its stability in practical applications. The traditional antioxidant addition method is usually to quantitatively dilute the antioxidant mother liquor into the tank of the outbound tank truck when the biodiesel is out of the warehouse, and then the biodiesel is mixed evenly with the antioxidant dilution while leaving the warehouse. However, there are some problems, such as uneven mixing and the mixed liquid being relatively viscous and easy to adhere to the inner wall of the mixing tank.
