摘要
In this research,a solid 1%Li/Ca-La mixed oxide catalyst was prepared using co-precipitation method followed by wet impregnation.The prepared catalyst was used in the transesterification reaction of canola oil and methanol for biodiesel synthesis.The effects of calcination and reaction temperatures were investigated on the activity of the catalyst.In addition,rate of the reaction was studied through a kinetic model for which parameters were determined.Surface properties and structure of the catalyst were characterized through the powder X-ray diffraction(XRD),thermogravimetry/derivative thermogravimetry(TG/DTG),and Fourier transform infrared spectroscopy analysis.All these emphasized that the performance of the catalyst corresponded to the generation of the active sites and their thermal activation.
