Optimization and Characterization of Biodiesel Synthesis from Neem Seed Oil

Résumé fourni par la source

Bd was produced by transesterification of refined NSO with MeOH and CaO catalyst using batch mode.Physicochemical properties of NSO and Bd as an alternative diesel fuel were characterized using ASTM fuel test standards.The FA composition and functional groups of Bd were investigated using GC-MS and FT-IR, respectively.The effect of basic parameters such as reaction catalyst Ct, MeOH/oil molar ratio, reaction T and time, and SS were determined using batch mode.These process parameters were optimized using RSM and ANOVA.The importance of various process parameters and their combined effects on transesterification performance was determined through CCD.Statistical analyzes of the data led to the development of a second-order quadratic polynomial regression model that established the relationship between Bd yield and process variables.The model was able to adequately predict Bd yield with R 2 value of 0.9942.The obtained results were in good agreement with published data for Bd from other vegetable oils, as well as with various international standards for this product.An optimal yield of 94% was achieved under optimal conditions of catalyst Ct (4 wt%), MeOH/oil molar ratio of 8:1, T of 55 °C, time of 60 min and SS of 400 rpm.The results show that Bd produced using alcohol in the transesterification process improved CP and CFPP properties.
