چکیده انگلیسی
Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/γ-Al2O3 particles were conducted in batch stirred and packed-bed tubular reactors at 60â¯Â°C. The proposed three-parameter kinetic model describing the overall reaction with a variable mechanism was successfully applied to both batch and continuous reactions. The process optimization was done using the response surface methodology combined with a central composite design. The obtained optimal catalyst concentration, methanol-to-oil molar ratio and reaction time for the batch reaction were 0.55% (CaO to the oil), 9:1 and 5.22â¯h, respectively. In the continuous process, the catalyst was highly active stable and slightly leachable during 30â¯h. The deactivation of the catalyst was due to massive deposition of the organic molecules from the reaction mixture, which sheltered the catalytically active sites on the catalyst surface.
