Kinetics of the sunflower oil ethanolysis using CaO as catalyst
The ethanolysis of sunflower oil catalyzed by calcium oxide was studied in wider ranges of the reaction conditions: temperature 65-75°C, ethanol-to-oil molar ratio 6:1-18:1 and catalyst loading 10-20% in order to determine the reaction kinetics. The proposed kinetic model of the sunflower...

| description | The ethanolysis of sunflower oil catalyzed by calcium oxide was studied in
wider ranges of the reaction conditions: temperature 65-75°C,
ethanol-to-oil molar ratio 6:1-18:1 and catalyst loading 10-20% in order to
determine the reaction kinetics. The proposed kinetic model of the sunflower
oil ethanolysis included the changing and first-order reaction mechanism
with respect to triacylglycerols and fatty acid ethyl esters. The kinetic
parameters were determined and correlated with the process variables. The
Arrhenius equation could be applied to the reaction rate constant with the
activation energy of 94.0 kJ/mol. The proposed kinetic model showed a good
agreement with the experimental data with the mean relative percentage
deviation of ±13% (based on 256 data points). [Projekat Ministarstva nauke
