Optimization of <i>Jatropha</i> Biodiesel Production by Response Surface Methodology

Cost of biodiesel is primarily because factors such as the feedstock, production process and materials. Apparently, final product a bit expensive compared to fossil diesel fuel. While non-food feedstock high oil content Jatropha curcas has been proposed reduce cost due promising two-step approach hydro-esterification can possibly offset for resource with free fatty acids. Most importantly, optimization materials expected wastage, enhance purity generate less wastewater. However, optimizing generation dauntingly elusive several parameters are needed be considered holistically. In this study, Response Surface Methodology (RSM) was employed optimize yield conversion from J. hydrolysate. An optimum Yield 96% achieved both responses an temperature value 60°C, 4 wt% catalyst loading 6 hrs reaction time. Findings imply that study hydrolysate acid methyl esters using face centered central composite design Design Expert 6.0.8 ensure product, conserve energy waste providing significant frontier in pricing.
