Item Datasets on process transesterification of binary blend of oil for fatty acid ethyl ester (FAEE) synthesized via the ethanolysis of heterogeneous doped catalyst(Elsevier, 2020-08-01) Adepoju, T.F.; Ibeh, M.A.; Babatunde, E.O.; Abegunde, G.S.; Adepoju, P.O.; Asquo, A.J.; Osueke, C.O.The data employed the blend of waste used oil and beef tallow for the synthesis of fatty acid ethyl ester (FAEE) via ethanolysis of developed catalyst from calcined fermented cocoa pod husk powder (CFCPHP) doped with burnt cocoa pod husk powder (BCHP). Characterization of the developed doped catalyst (DDC) was carried out using FTIR, SEM, XRD, and BET adsorption analysis, while the basic strength of the DDC was tested through reusability test data. Mathemati- cal optimization of the process condition was carried out through Box-Behnken Experimental Design (BBED) in 29 runs with variations in four variables as catalyst concentration (1.5 to 3.5 wt.%), reaction time (60 to 100 min), ethanol/oil molar ratio (EtOH/OMR) of 3 to 7, and reaction temperature (60 to 80 °C). The FAEE quality was ascertained by determining its fuel properties.Item Methanolysis of CaO based catalyst derived from egg shell-snail shell-wood ash mixed for fatty acid methylester (FAME) synthesis from a ternary mixture of Irvingia gabonensis -Pentaclethra macrophylla - Elais guineensis oil blend: An application of simplex lattice and central composite design optimization(Fuel, 2020-09-01) Adepoju, T.F.; Ibeh, M.A.; Babatunde, E.O.; Asquo, A.J.Considering the large number of wastes produced as wood ash, snail and eggshells around the globe, CaO based catalyst was derived from the thermal treatment of carbon carbonate obtained from the mixture of these wastes for methanolysis synthesis of FAME from the ternary mixture (33:33:34) of Irvingia gabonensis, Pentaclethra macrophylla, and Elais guineensis oil was carried out in this study. Calcined blend catalyst (CBC) was well characterized by SEM, EDX-ray, FTIR and BET analysis. The strength of the basicity of the catalyst was tested by catalyst recyclability via methanolysis of CaO transesterification of ternary blend oil to FAME. Results showed a maximum FAME yield of 98.00 (wt%) with the statistical optimization prediction of 97.33 (wt%) at a reaction time of 64.71 min, catalyst amount of 4.5 wt%, reaction temperature of 61.61 °C, and methanol/oil molar ratio of 8:1 (ml/ml), the predicted value was validated in triplicate to obtain an average FAME of 97.22 (wt%). Catalyst reusability was stopped at the 3rd cycle due to decrease in it activity. Statistical optimization through analysis of variance further confirmed the remarkable significant effects of the independent variables with pvalue < 0.0001. Physicochemical properties of the FAME conformed with biodiesel recommended standard. Results also show that the CaCO3 contained in the mixture of wood ash, snail and eggshells is a promising source for CaO catalyst production for industrial application.
