  • Abstract Biodiesel is a renewable fuel, most commonly produced from transterification of
    vegetable oils with low molecular weight alcohols using homogeneous catalyst. In
    homogeneous catalytic reaction, soap formation will hinder the reaction process and also
    cause environmental pollution. Finally, extra cost for the neutralization, distillation, and
    washing steps needed to purify the final product is too high for industries. In this study,
    heterogeneous solid catalyst (K3PO4) was used for transesterification reaction in batch
    and well-stirred reactor. The experimental design methodology was employed to find the
    main influencing factors, including reaction temperature, methanol to oil molar ratio,
    catalyst amount and reaction time. The experimental results show that increasing the
    reaction temperature has little effect on the biodiesel yield, increasing the molar ratio of
    methanol to oil or catalyst amount can increase the biodiesel yield. The HPLC analysis
    results show triglyceride decreases with the reaction time, while diglyceride and
    monoglyceride increases with the reaction time. The 3-step kinetic model can be used to
    predict the transesterification kinetic curves satisfactorily.
