| Abstract: | With K2CO3 and nanometer CaCO3(self-prepared) as raw materials,and K2CO3 dosage of 50%,the K2CO3/CaO solid-base catalyst was prepared by calcination at 750 ℃ for 3 h,which was characterized by XRD,FT-IR and TG-DSC.The catalyst obtained was then used to prepare biodiesel.The result shows that under the optimum conditions that the mass fraction of nanometer K2CO3/CaO is 3%,mole ratio of alcohol to oil is 12 ∶1,temperature is 70 ℃,reaction time is 1 h,the biodiesel yield comes up to 99.1%,which is featured by high catalytic activity,simple process,no effluents discharge,no corrosion to equipment,short time and less cost. |
