Article Highlights • Kinetics of methanolysis reaction catalyzed by calcium-based catalysts • Kinetic model involves TAG mass transfer and chemically controlled regions • Effects of reaction conditions on parameters of the kinetic models are analyzed Abstract The kinetic model, which was originally developed for sunflower oil methanolysis catalyzed by CaO⋅ZnO, was examined for several other calcium-based catalysts like neat CaO, quicklime and Ca(OH) 2 . This model including triacylglycerols

Hence, this model is recommended for modeling the kinetics of sunflower oil methanolysis over calcium-based catalysts under widely ranging reaction conditions.
