ThisvariationcanbebetterobservedinFigure8,which isazoomedpartofFigure7 restricted
to the first fewminutes.Considering that the idea is to obtainpurebiodiesel, independent of
the reactionconditions, it isquitenatural that the finalvelocities (when thehighest concentra-
tionofbiodiesel ispresent)are close toeachother.
5.Looking into theresults indetails
Let us analyse the effect of each parameter (catalyst and rotation) on the final biodiesel
conversion.
