| description | A nanocomposite comprising cellulose and nanomagnetite
based on rice husk cellulose was used as the catalyst for the formation of methyl
esters from oleic acid as an alternative method for biodiesel production. The
resulting nanocomposite properties supported by FTIR, XRD, SEM and TEM
characterization revealed that nanomagnetite Fe3O4 had
impregnated the acetylated nanocellulose. The nanomagnetite Fe3O4 obtained
had an average size of 30 nm. The best conversion of oleic acid to methyl
esters for the catalytic application of the nanocomposite was 89.21%, which was
achieved at a reaction temperature of 60°C, reaction time of 5 hours, catalyst
concentration of 1.5 wt.%, and ratio of oleic acid to methanol of 3:1. Kinetic analysis
at different temperatures (40, 50, 60 and 70°C) was performed, and a low
activation energy of 16.56 kJ/mole was obtained. These results indicate that
the biopolymer-based nanocomposite utilizing nanocellulose from rice husks
composited with inorganic Fe3O4 nanoparticles has good
potential for use as a green biocatalyst, and the proposed reaction can be used
as an innovative new method to produce biodiesel in the future. |
