Continuous Integrated Process of Biodiesel Production and Purification—The End of the Conventional Two-Stage Batch Process?

In this research, optimization of the integrated biodiesel production process composed transesterification edible sunflower oil, catalyzed by commercial lipase, with simultaneous extraction glycerol from reaction mixture was performed. Deep eutectic solvents (DESs) were used in as and media. For two systems, choline chloride:glycerol (ChCl:Gly) chloride:ethylene glycol (ChCl:EG), respectively, optimal water content, mass ratio phase containing reactants (oil methanol) an enzyme a DES (mass phases), molar deep solvent constituents determined using response surface methodology (RSM). Experiments performed ChCl:Gly resulted higher yield efficiency, namely, phases 1:1, fraction 6.6%, 1:3.5 to be conditions. When batch reactor under conditions, 43.54 ± 0.2% 99.54 0.19% efficiency (t = 2 h). Unfortunately, free content than one defined international standards (wG > 0.02%); therefore, microsystem enhance transfer. Gaining same below 0.0019 0.003%), proved good direction for future optimization.
