(476b) Transesterification of Camelina Sativa Oil Using Heterogeneous Metal Oxide Catalysts

Camelina sativa oil provides a reliable solution for the biodiesel production by providing a sustainable, low-input bio-fuel feedstock option in some climates. In the present study, optimization of transesterification of camelina sativa oil using different heterogeneous metal oxide catalysts i.e., BaO, SrO, MgO and CaO were evaluated. The results of comparative experiments showed that most effective catalyst was 1 wt% BaO which showed a more than 80% yield of camelina biodiesel in 3 hours at 100ºC. The relative order of effectiveness was BaO > SrO > CaO > MgO. The catalyst characterization, such as XRD, SEM, and BET were also studied in detail. The most important variables affecting the methyl ester yield during the transesterification reaction are the molar ratio of alcohol to oil, the catalyst amount and the reaction temperature. The fuel properties of biodiesel produced were compared with ASTM standards for biodiesel.
