| Résumé : | Process parameter evaluation and catalyst performance study was conducted for biodiesel production using jatropha curcas, waste cooking, and camelina sativa oils. Conversion of triglycerides to methyl esters involves esterification and/or transesterification, depending on the nature of the feedstock. A two-step transesterification process (acid esterification followed by alkali transesterification) was employed to produce biodiesel from high free fatty acids (FFA) in jatropha curcas and waste cooking oils, and a single-step transesterifcation process (alkali transesterifcation) was used for camelina sativa oil conversion. Catalyst selection is vital in transesterification process because it determines biodiesel yield and cost. Transesterification of jatropha curcas and waste cooking oil was optimized by using H2SO4 and ferric sulfate catalysts in the acid esterification step and a KOH catalyst in the alkali transesterification, respectively. Heterogeneous metal oxide catalysts including BaO, SrO, MgO, and CaO were used for the transesterification of camelina sativa oil. |
