Resumen:
In this work biodiesel (BD) purification was carried out with two lab-made solvent resistant compositenanofiltration (NF) membranes of poly(vinylideneflouride) (PVDF) as a support and poly(dimethylsiloxane)(PDMS) as coating layer. BD was obtained from the esterification of partially refined soy oil with bioethanol(EtOH) and NaOH as catalyst. The best BD purification performance was achieved with the PVDF-12SImembrane reaching retentions of 70% of glycerol, 69% of total glycerides, and 40% of soap. It wasremarkably that PVDF-SI membranes have an excellent stability for BD permeation, achieving a FluxRecovery Ratio of EtOH as higher as to 0.94 after 20 cycles of use.
