International Fuel Technology Inc. has developed an additive which improves the oxidative stability of biodiesel. The St. Louis-based company recently announced the results of tests conducted by the Bio-Energy Innovation and Testing Center at Montana State University-Northern.

In the test project, International Fuel Technology's DieseLIFT BD-3 additive was blended with biodiesel fuel samples produced from various feedstocks, including camelina, soybean and a camelina-coconut blend. None of the untreated biodiesel samples were able to meet the European specification for EN 14112 oxidative stability. Treatment with BD-3 improved the oxidative stability index by two to 10 times, according to the Montana State University study.

Researchers and industry experts in Montana have a particular interest in camelina which is being developed in the state as a promising alternative crop. However, biodiesel made from camelina shows a low oxidative stability rating lower than sunflower and soybean biodiesel which are also on the low end of the oxidative stability index. Improving the oxidative stability increases the shelf life of the product.

Testing results from the Montana State University-Northern study and a European laboratory are detailed in a company bulletin available on International Fuel Technology's Web site: http://internationalfuel.com/pdfs/BD3-BULLETIN-JUN-08-1.pdf.
