Oxidative Stability and Molecular Reactivity of Biodiesel from Castor and Cottonseed Oil Blends by Homogeneous and Heterogeneous Catalysis

Energy Technology, EarlyView.
The oxidative stability of biodiesel from homogeneous and heterogeneous catalysis of castor/cottonseed oil blends is studied. Castor oil's ricinoleic acid improves oxidative stability, acting as a natural antioxidant. Yet, HT catalysis led to lower stability due to catalyst leaching.
