Antioxidant Additives to Improve the Oxidative and Thermal Stability of Biodiesel Fuel

- Summary
- A significant problem associated with the commercial acceptance of biodiesel fuel is poor oxidative stability. The presence of high levels of unsaturated fatty acid methyl esters (FAME) make biodiesel very susceptible to oxidations as compared to petroleum diesel. Oxidative processes can lead to the formation of insolubles which can potentially plug fuel filters and injection systems. The increased acidity and increased peroxide value as a result of oxidation reactions can also cause the corrosion of fuel system components, hardening of rubber components, and fusion of moving components.
Researchers at WSU’s National Biofuels Energy Laboratory have identified antioxidant additives for biodiesel fuel made from a variety of feedstocks that improve the long term storage stability of B20 and B100 fuels and enable them to exceed the ASTM D6751-07 standard by as much as four times.
