摘      要：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 *** anthill-eggshell composite(AEC)catalyst was prepared using an incipient wetness impregnation *** 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 *** on the CCD,two quadratic models were developed to correlate the AEC preparation parameters to the two *** of variance(ANOVA)was performed to verify the reliability of the models and also,identify the factor that mostly affects the experimental design *** results showed that the predicted values of biodiesel yield from the models for the two oils agreed reasonably well with the experimental *** optimum conditions for the preparation of AEC catalyst for the transesterification process were calcination temperature of 1000℃,calcination time of 4 h,and anthill proportion of 20% to achieve 97.13%yield of biodiesel from virgin vegetable *** the same optimum parameters,the yield of biodiesel from waste vegetable oil was found to be 70.92%.
