  • kinetics of sunflower oil methanolysis at low temperatures
    Bioresource Technology, 2008
    Co-Authors: Olivera S Stamenkovic, Zoran B. Todorović, Miodrag L. Lazić, Vlada B. Veljković, Dejan Skala
    Abstract:

    Abstract The kinetics of the sunflower oil methanolysis process was studied at lower temperatures (10–30 °C). The sigmoidal kinetics of the process was explained by the mass transfer controlled region in the initial heterogenous regime, followed by the chemical Reaction controlled region in the pseudo-homogenous regime. A simple kinetic model, which did not require complex computation of the kinetic constants, was used for simulation of the TG conversion and the FAME formation in the latter regime: the fast irreversible Second-Order Reaction was followed by the slow reversible Second-Order Reaction close to the completion of the methanolysis Reaction. The mass transfer was related to the drop size of the dispersed (methanol) phase, which reduced rapidly with the progress of the methanolysis Reaction. This was attributed to the formation of the emulsifying agents stabilizing the emulsion of methanol drops into the oil.

  • kinetics of the base catalyzed sunflower oil ethanolysis
    Fuel, 2010
    Co-Authors: Ana V Marjanovic, Olivera S Stamenkovic, Zoran B Todorovic, Miodrag L Lazic, Vlada B Veljkovic
    Abstract:

    The kinetics of the sunflower oil ethanolysis process using NaOH as a catalyst was studied at different Reaction conditions. The Reaction system was considered as a pseudo-homogeneous one with no mass transfer limitations. It was also assumed that the chemical Reaction rate controlled the overall process kinetics. A simple kinetic model consisting of the irreversible Second-Order Reaction followed by the reversible Second-Order Reaction close to the completion of the ethanolysis Reaction was used for the simulation of the triglyceride conversion and the fatty acid ethyl ester formation. The proposed kinetics model fitted the experimental data well.
