Abstract
As part of a survey of biodiesel quality and stability in the US, 27 B100 samples were collected from blenders and distributors nationwide. The samples included four produced from waste oils, one from tallow, and the balance from soy. A series of chemical analyses and oxidation stability tests were conducted to reveal the factors influencing B100 stability. A typical US biodiesel exhibits 5 mg/100 mL of deposits on the ASTM D2274 accelerated stability test and < 1 hr induction time on the EN 14112 Rancimat stability test. The formation of insolubles on the D2274 test was influenced by the antioxidant content, polyunsaturate content, and the presence of high levels of mono and di-glycerides. The Rancimat induction time was mainly influenced by the polyunsaturated content and to a lesser extent by the antioxidant content. This is an abstract of a paper presented at the 231th ACS National Meeting (Atlanta, GA 3/26-30/2006).
