  7. Abstract:
  8. This study aims at synthesizing and investigating of heterogeneous catalysts for biodiesel production as an alternative to fossil fuel with the transesterification of oil and methanol. Three main sections of this thesis concern the synthesis of nano-catalysts, characterization analysis, and investigation of the transesterification reaction under different condition. Two series of heterogeneous catalysts, including different molar ratios of X%Li/Ca-La (X=0-7%) and Ca/Talc (Ca, 3Ca/1Talc, 1Ca/1Talc, 1Ca/3Talc, Talc) has been synthesized as active and stable catalysts to study the transesterification reaction of canola oil and methanol for biodiesel production. Prepared catalysts have been characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), and Brunaur-Emmett-Teller (BET) surface area studies, in order to illustrate the structure and morphology of the catalyst. After reaction studies in the reactor under different reaction conditions and investigation of effective parameters, the reaction product showed a clean and green replacement for fossil fuels. Under optimal reaction conditions (methanol/oil ratio of 15/1, 5% wt% catalyst, 65 C reaction temperature, and 700C calcination temperature), 96.3% fatty acid methyl ester (FAME) yield was obtained in 2.5h of reaction time. The biodiesel yield calculated by GC-Mass was higher than similar studies and almost met the EN standard. Moreover, the catalyst could be reused up to 4 cycles without significant loss of performance
