Kinetic Modeling of Supercritical Interesterification with Heterogeneous Catalyst to Produce Methyl Esters Considering Degradation Effects

In this study, it has been proposed a process model for catalytic supercritical interesterification considering degradation reactions at high temperatures. Kinetic parameters of soybean oil and methyl acetate (MeA) reaction using Ca–Mg–Al mixed oxide as catalyst considering main and intermediate reactions were estimated. Experimental data varied between 200 and 350 °C, a catalyst concentration of 2, 5, and 10 wt % and molar ratio (MeA:Oil) of...
