| Abstract: |
| In this research, the transesterification process of edible oil waste was investigated using pumice catalyst doped with nano calcium oxide. The catalyst was prepared through the process of nano-calcium oxide doping on black pumice. Response surface method and central composite experimental design were used to design the experiments. The effects of the variables of molar ratio of methanol to oil, catalyst concentration, reaction time and reaction temperature at different levels on the efficiency of the biodiesel production process were investigated. The results showed that the independent variables of molar ratio of methanol to oil and catalyst concentration had a significant effect at the 5% level on biodiesel production efficiency, and the independent variable of catalyst concentration had the greatest effect. The results of variance analysis for the interaction effect of independent variables showed that the interaction effect of catalyst concentration variables in time has a significant effect at 1% level on biodiesel production efficiency. The results of the optimization of the biodiesel production process showed that the maximum amount of biodiesel production efficiency in the conditions of 5.4942 molar ratio of methanol to oil, 0.762% weight of catalyst concentration, reaction time 90.675 minutes and the reaction temperature was 47.877 Celsius. Under these conditions, the yield of biodiesel produced was 89.480%. The results of the GC-MS test showed that biodiesel produced from the waste of edible oils consists of linoleic acid (28.52%), palmitic acid (17.62%), oleic acid (21.38%) and stearic acid (7.07%). |
