Abstract :
Acid oil having free fatty acids and glycerides produced through soybean soapstock can reduce the cost of biodiesel production. Optimization of H2SO4 catalyzed process was completed by carrying out a central composite design and a quadratic polynomial model was obtained. When methanol/oil molar ratio was 35.49:1, catalyst was 11.59% relative to the weight of acid oil, reaction time was 4.58 hours, and the ester content of product was 95.03%, close to the theoretical critical value of 95.85%. This study provides a reliable theoretical basement for commercial biodiesel production from acid oil. This electronic document is a "live" template.
