| description | Currently, the catalytic efficiency and reusability of the solid base
catalysts cannot meet the demand of industrial biodiesel production under low
temperature. The purpose of this study is to define the kinetics of
heterogeneous transesterification process which might be used for the
prediction of the biodiesel synthesis at high temperature and pressure. The
focus in this study was paid to recently reported data obtained with
different catalysts used for biodiesel synthesis in a batch reactor at high
temperatures. It was shown that three kinetic models that include: a)
irreversible first order reaction; b) reaction with changeable order; and c)
resistances of mass transfer and chemical reaction at active sites of the
catalyst could be applied for predicting the effect of high temperature of
the transesterification. The apparent reaction rate constant of the
irreversible first order reaction was determined, as well as the parameters
of the other two, more complicated kinetic models. The best agreement was
obtained with the more complicated models and the mean relative percent
deviation between calculated and experimentally determined triacylglycerols
conversion for these kinetic models is between 3 and 10%. [Projekat
