Kinetic Investigations of Biodiesel from Cottonseed Oil and Ethanol by Transesterification in Biomaterial and its Application

Abstract:

The kinetics of transesterification for biodiesel produced by cottonseed oil and ethanol in catalyst (potassium hydroxide) was investigated. The reaction of transesterification can be described by pseudo second order model for the initial stages of the reaction, followed by zero order reaction. The reaction rate constants for transestentcation of cottonseed oil with ethanol at 40°C, 60°C and 78°C are 0.0996, 0.1126and0.1286 L•mol-1/min-1 respectively, and the activation energy of transesterification is 21.6075kJ/mol．
