论文摘要
The performances of the response surface methodology（RSM） in connection with the Box–Behnken, face central composite or full factorial design（BBD, FCCD or FFD, respectively） were compared for the use in modeling of the NaOH-catalyzed sunflower oil ethanolysis. The influence of temperature, catalyst loading, and ethanol-to-oil molar ratio（EOMR） on fatty acid ethyl esters（FAEE） content was evaluated. All three multivariate strategies were efficient in the statistical modeling and optimization of the influential process variables but BBD and FCCD realization involved less number of experiments, generating smaller costs, requiring less work and consuming shorter time than the corresponding FFD. All three designs resulted in the same optimal catalyst loading（1.25% of oil） and EOMR（12:1）. The reduced two-factorinteraction（2 FI） models based on the BBD and FCCD defined a range of optimal reaction temperature（25 °C–75 °C） and 25 °C, respectively while the same model based on the 33 FFD appointed 75 °C. The predicted FAEE content of about 97%–98.0% was close to the experimentally obtained FAEE content of about 97.0%–97.6% under the optimal reaction conditions. Therefore, the simpler BBD or FCCD might successfully be applied for statistical modeling of biodiesel production processes instead of the more extensive,more laborious and more expensive FFD.
