Usually, the reaction time for the chemical biodiesel making is shorter than the
biodiesel creation via an enzymatic catalyst.
The results displayed that ethanol provided a greater production of biodiesel in
contrast to methanol (Fig. 1.15).
Although, the difference between the yield of ethanol and methanol was small,
but in terms of cost and economic benefit and advantages such as higher cetane
number, lower cloud points, ethanol can be more attractive as compared to methanol.
Since ethanol would now be able to be delivered from sustainable and ease
farming biomass, along these lines, ethanol biodiesel shows up as a 100% inexhaustible other option (Nasaruddin et al. 2013, 2015).
