“…13,16,17 In this process, the membrane acts as a barrier to the glycerol molecules, which are associated with other ones by hydrogen bonds increasing the particle size, while the molecules of the fatty acid esters pass the membrane pores, getting in the permeate and separating from the glycerol. 18 Ceramic membranes 19,20 and synthetic polymer ones [21][22][23] have been the most exploited for biodiesel purification, despite the lower reproducibility and higher cost of the preparation process. Atadashi et al 24 used a membrane filtration system to remove free glycerol and soap from crude biodiesel.…”

Biodiesel purification by water washing has been proved to be an unattractive process from an economic and environmental point of view. In this work, we propose the use of regenerated cellulose membranes from peanut shell as an alternative in the biodiesel purification. The preparation of the membranes was optimized from a central composite design, resulting in dense and non-porous membranes. However, in contact with biodiesel, the membranes undergo expansion due to the retention of methanol, water, and glycerol molecules, allowing the permeation of fatty acid methyl esters. The filtered biodiesel presents quality parameters, such as total ester content of 98.3 ± 1.4% and free glycerol content < 0.02%, in agreement with the main regulatory agencies. The regenerated cellulose membranes from peanut shell are easily prepared, with high repeatability (relative standard deviation (RSD) < 1.8%) and are presented as an economical and environmental solution for the biodiesel purification.
