The kinetics of heterogeneous methanolysis of sunflower oil was studied at   60°C using mechanochemically synthesized CaO∙ZnO as catalyst. Influence of   agitation speed, catalyst amount and methanol to oil molar ratio on the rate   of reaction was analyzed. The rate of the process depends on the two   resistances - mass transfer of triglycerides to the catalyst surface and   chemical reaction on the catalyst surface, which are defined as the values of   the overall triglyceride volumetric mass transfer coefficient, kmt,TG, and   the effective pseudo first-order reaction rate constant, k, respectively.   These kinetic parameters actually determine the value of the apparent   reaction rate constant, kapp, whose change with time is defined with the   change of triglyceride (TG) conversion. The kinetic model was proposed and   the model parameters determined. [Projekat Ministarstva nauke Republike   Srbije, br. 45001
