Process optimization of Xanthoceras Sorbifolia Bunge Oil-based Biodiesel Production by Response Surface Methodology
To investigate the potential application of Avena sativa oil in the biodiesel industry,we utilized SO42-/ZrO2-CeO2-Hangzhou 2#soil(SZCe-HJ)as a catalyst.The central composite(CCD)experimental design method was employed,with the reaction temperature(X1),alcohol-oil molar ratio(X2),catalyst dosage(X3),and reaction time(X4)as independent variables.The biodiesel yield(Y)was considered as the response value,and a mathematical model was established by fitting the experimental data.The results demonstrated that the model accurately predicted the biodiesel yield of SZCe-HJ-catalyzed Avena sativa oil preparation.The optimum conditions for maximum yield were found to be an alcohol-oil molar ratio of 8.21:1,catalyst dosage of 2.66 wt.%,and reaction time of 8.65 h.Under these conditions,the highest biodiesel yield achieved was 62.76%.
