Abstract—This work investigates the use of Li
2CO
3-modified waste peanut husk ash as the solid base catalyst for the biodiesel production. The prepared waste peanut husks as the solid base catalyst are characterized by XRD, BET, SEM and TGA for the physical and chemical properties. In the present study, the biodiesel is synthesized from soybean oil through a transesterification reaction catalyzed by the solid base catalyst. Under the optimal reaction conditions of methanol/oil molar ratio 12:1, 5% (wt/wt oil) catalyst amount, and a reaction temperature of 65 oC for 4 h, there is a 98.4 % conversion to the biodiesel from soybean oil.
