Abstract:

Biodiesel is a domestic, renewable fuel that is gaining wide acceptance, especially in Europe.  When blended with conventional petroleum diesel, biodiesel reduces hydrocarbon, particulate and carbon monoxide emissions, while having minimal to no effect on NOx.  It also improves lubricity, lowers sulfur, and has a high cetane number.  The promise of biodiesel is tremendous, but some significant obstacles remain to its complete acceptance by diesel engine manufacturers, most significantly with respect to oxidative stability.  This proposed project will investigate the factors associated with biodiesel oxidative stability, including natural and synthetic antioxidants, storage and processing conditions.  Results of this project will provide much needed guidelines to industry with regards to storage conditions and antioxidant additive levels.  Additionally, biodiesel production changes will be recommended which will optimize the preservation of natural antioxidant levels in the fuel.  Finally, factors required for the development of a user-level sensor for biodiesel oxidative stability will be quantified.
