sounddecreases until stabilized, demonstrating that themaximumconversionwas reached. 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.
