3.2. Influence of the parameters on the biodiesel yield
Three-dimension surface plots of the predicted biodiesel yield
are illustrated in Fig. 3. Based on the model analysis, it can be
observed that reaction temperature and catalyst amount have
positive effect on the biodiesel yield. This is also represented in
the Fig. 3(a): the yield of biodiesel presents an increase trend with
the increase of reaction temperature and catalyst amount.
