Abstract
Sewage sludge and waste cooking oil based biodiesel (WCOB) recently gaining popularity for a fair amount of lipid content for biodiesel production. In this study, for the first time sewage sludge biodiesel (SSB) based blend was subjected to engine performance analysis. SSB has relatively higher saturated fatty acid content and reduced polyunsaturated fatty acid content. While WCOB has low saturated methyl esters and very high unsaturated methyl ester concentration. Hence, effect of fatty acid structure on performance and emission were also monitored. On the basis of performance WCO30 (30 % v/v WCOB and 70 % v/v diesel blend) found better alternative with low break specific fuel consumption and lesser exhaust gas emission compared to SSB30. However, decent performance was also witnessed for SSB30. It was observed that fatty acid profile has negligible effects on the performance parameters. Whereas, significant variation in NOx, CO and HC emission were noted with change in individual fatty acid methyl ester contents. Utilising SSB30 and WCO30 reduced the CO emission by 12.82% and 10.39% respectively. Saturated fatty acid methyl ester rich SSB30 resulted 9.09% higher NOx emission than petroleum diesel. Hydrocarbon emission were increased by the presence of unsaturated fatty acid methyl esters.
