Abstract

Abstract: This work focuses on better understanding of how or in what way the individual polyunsaturated fatty acid alkyl esters contained in biodiesel are affecting the fuel properties. Effect of two such important polyunsaturated fatty acid alkyl esters (methyl linoleate and methyl linolenate) are analysed by optimizing their concentration using Response Surface Methodology. Alterations in the concentration of these fatty acid esters have produced evident changes in biodiesel fuel properties. Statistical analysis with R 2 values of 0.8914 and 0.9845 imply that the model is substantial and fatty acid esters have vital impact on fuel density. Results suggest that methyl linolenate has significant effect on specific gravity of biodiesel proposing that methyl linolenate regulates the density of the fuel. Hence, enriching the biodiesel source with defined concentration of methyl linolenate might govern some critical parameters like engine output power and cetane number of fuel. Furthermore, biodiesel blends of five different oils have been compared to examine the scope of modifications needed to achieve higher percentage of biodiesel in the practically used blends. Abstract : Technical limitations of biodiesel fuel can be resolved by defining the optimum concentration of each fatty acid ester and by ascertaining interdependence of the fuel properties and fatty acid methyl esters in biodiesel composition. Methyl linolenate is found to regulate the density of the fuel thereby providing aid to various mechanical problems of fuel like engine output power, ignition quality and cold flow behaviour
