The stability of w-ROL in [Bmim][BF(4)] was greatly enhanced by cross-linking the biocatalyst with glutaraldehyde. All rights reserved. Methanol elimination by evaporation from the biodiesel phase or from both phases present after the reaction leads to a reversion of the reaction because of the shift of equilibrium toward the reactants. For that, SuperPro Designer v. 9.0, a process design commercial software, was used with production process data collected from the literature. The influence of reaction variables including; molar ratio of methanol to oil (6:1-12:1), temperature (55-65 degrees C) and catalyst concentration (0.6-1.8 wt.%) and residence time (20-180 s) under various flow rates of reactants (1-11 ml min(-1)) on Fatty Acid Methyl Ester (FAME) transesterification reaction was studied.

In this work, this process stage is studied, i.e., methanol evaporation before glycerine and biodiesel phase separation, and the effects that different homogeneous catalysts have on this operation. Biodiesel, an alternative diesel fuel derived from vegetable oil, animal fat, or waste vegetable oil (WVO), is obtained by reacting the oil or fat with an alcohol (transesterification) in the presence of a basic catalyst to produce the corresponding mono-alkyl esters. Compared to conventional method, the reaction time of the way of microwave assisted transesterification was shorter.
