Metal Additives Influence in the Storing Stability Degradation of Biodiesel

Recently, biodiesel is used as an alternative fuel to reduce the air pollution. However, storage stability comes as it reduces the biodiesel properties after it been stored for a long period. This study was conducted to investigate the effect of storage duration on the stability degradation of biodiesel and the influence of metal additives nanoparticles blend to retard the deterioration of biodiesel. Biodiesel was synthesized using transesterification of waste cooking oil Gas Chromatography was performed to characterized the elements of biodiesel. Silver, manganese and iron nanoparticles were synthesized following sol-gel method. Nanoparticles were blended with biodiesel in concentration of 100 and 500 ppm using the ultrasonicator bath. Storage stability observation was performed according to ASTM4625 method which is 43 °C for one week. Gas Chromatography peaks shows similar components as standard biodiesel such as methyl palmitate, methyl stearate and methyl linoleate. Density and acid value were sis results proved that nanoparticles can help to retard the stability degradation of biodiesel.
