Optimization of biodiesel production parameters from Prosopisjuliferaseed using definitive screening design

The concept of waste to valuable products is a hot topic with more explorations going on worldwide to minimize the environmental pollution and wastage of food-based feedstocks. In this work, biodiesel was produced from Prosopis julifera seed oil using ethanol as solvent and magnesium nanocatalyst an...

description The concept of waste to valuable products is a hot topic with more explorations going on worldwide to minimize the environmental pollution and wastage of food-based feedstocks. In this work, biodiesel was produced from Prosopis julifera seed oil using ethanol as solvent and magnesium nanocatalyst and the process was optimized by employing an advanced statistical optimization method; definitive screening design. The maximum biodiesel yield from Prosopis julifera seed was found to be 32.5%. Acid esterification and transesterification were applied to minimize the acidity. Acidity of the P. julifera oil was initially reduced to 1.52 mg KOH/g using acid catalyst H(2)SO(4), and then to 0.88mg KOH/g by transesterification process using magnesium oxide. Optimum biodiesel conversion efficiency of 94.83% was achieved under 10:1 ethanol-to-oil ratio, 5% magnesium oxide concentration, 80 min reaction time, 45 °C reaction temperature and 1000 rpm agitation rate. The transesterification reaction was found to be highly affected by the ethanol-to-oil ratio and catalyst concentration. The results showed that the catalytic activity of the magnesium oxide was sufficient for the production of biodiesel from P. julifera seed oil. The fuel properties were evaluated according to ASTM standards. FTIR analysis confirmed the existence of functional groups with respect to the fingerprint region of P. julifera ethyl esters. The Definitive screening design method can be suggested as an alternative method for the optimization of process parameters within limited materials and number of experiments. The findings suggest that this method of production of biodiesel from P. julifera seed oil shall open up new possibilities for a novel natural biofuel.
