摘要： 本研究的主要目的是以蚁丘和鸡蛋壳为原料，制备一种复合材料，并将其应用于以植物油和废弃植物油为原料合成生物柴油。采用初期湿润浸渍法制备了蚁丘-蛋壳复合催化剂。采用中心复合设计（CCD）研究了催化剂制备参数（煅烧温度、煅烧时间和AEC中的蚁丘比例）对两种油制备生物柴油的影响。基于CCD，建立了AEC制备参数与两种响应的二次模型。通过方差分析（ANOVA）验证了模型的可靠性，并确定了影响试验设计响应的主要因素。优化结果表明，两种油模型的生物柴油产率预测值与实验值基本吻合。采用酯交换法制备AEC催化剂的最佳条件为：煅烧温度1000℃，煅烧时间4h，蚁丘比例20%，以植物油为原料制备生物柴油，产率为97.13%。在相同的最佳参数条件下，废植物油制备生物柴油的产率为70.92%。

Abstract: The primary goal of this study is to develop a composite material from the anthill and chicken eggshell and to use it as a catalyst for the synthesis of biodiesel from virgin and waste vegetable oils. The anthill–eggshell composite (AEC) catalyst was prepared using an incipient wetness impregnation method. Central composite design (CCD) was applied to investigate the effects of catalyst preparation parameters (calcination temperature, calcination time, and anthill proportion in the AEC) on the yields of biodiesel from the two oils. Based on the CCD, two quadratic models were developed to correlate the AEC preparation parameters to the two responses. Analysis of variance (ANOVA) was performed to verify the reliability of the models and also, identify the factor that mostly affects the experimental design responses. Optimization results showed that the predicted values of biodiesel yield from the models for the two oils agreed reasonably well with the experimental values. The optimum conditions for the preparation of AEC catalyst for the transesterification process were calcination temperature of 1000 °C, calcination time of 4 h, and anthill proportion of 20% to achieve 97.13% yield of biodiesel from virgin vegetable oil. At the same optimum parameters, the yield of biodiesel from waste vegetable oil was found to be 70.92%.
