“…In this study, the reaction temperature was kept constant at 60 • C and the agitation rate was kept constant at 300 rpm, as indicated in the esterification experiment [35]. Response surface methodology (RSM) and Box-Behnken Design (BBD) were used to investigate the primary reaction parameters (such as K 2 CO 3 /Glycerol ratio, catalyst (DES) concentration, and reaction duration) and optimize the reaction conditions for fatty acid methyl ester yield (FAME) production.…”

Increasing energy demand necessitates the production of sustainable fuels, which can be in the form of bio-fuels. One of such bio-fuels is biodiesel, which is typically produced via transesterification. The development of homogeneous catalyst that is relatively easy to synthesize, cheap, reusable, and environmentally friendly, is a major issue in transesterification reaction. The use of Deep eutectic solvent (DES) as catalyst, is believed to be a significant step in the direction of attaining a sustainable bio-economy. In this study, deep eutectic solvent was synthesized from different mole ratios of K2CO3/glycerol. The synthesized DES was used as catalyst in the transesterification reaction to produce biodiesel from Jatropha curcas oil. Box-Behnken design (BBD) was used to determine the factors that significantly affect the biodiesel yield. Optimum fatty acid methyl ester (FAME) yield of 98.2845% was achieved at optimum conditions of 1:32.58 mole ratio of K2CO3/glycerol, 8.96% w/w concentration of DES, and 69.58 minutes. GC-MS analysis revealed that the produced biodiesel contained 98.87% ester content. The properties of the biodiesel produced were characterized and found to agree with those of ASTM D6751-12 standard. Thus, suggesting the synthesized DES is a promising catalyst in the transesterification reaction to produce biodiesel from Jatropha curcas oil.
