Response Surface Optimization of Biodiesel Production with Rapeseed Filter Cakes by in Situ Alkaline Transesterification
An in situ alkaline transesterification process of rapeseed filter cakes with methanol assisted by petroleum ether was described in this article.Petroleum ether served as co-solvent and extraction solvent in the process.The response surface methodology (RSM) and 4-factor-5-1evel Central Composite design (CCD) were employed to evaluate the effects of synthesis parameters, X1 (reaction time), X2 (methanol/oil molar ratio), X3 (catalyst concentration) and X4 (petroleum ether/rapeseed filter cakes mass ratio), on the fatty acid methyl esters (FAMEs) yield of biodiesel.Based on ridge max analysis, the optimum conditions for synthetic condition were as follows: reaction time 102.85 min, methanol/oil molar ratio 112.67:1, catalyst concentration 2.85% wt/wt of oil and petroleum ether/rapeseed filter cakes mass ratio 0.34:1.The predicted FAMEs yield was 85.93 wt.% and actual experimental value was 83.97±0.81 wt.%.Furthermore, according to the RSM-based optimization results, a set of experiments were carried out to find the effect of ultrasound-assisted and microwave-assisted on the in situ alkaline transesterification reaction.
