| Summary: | Biodiesel. nontoxic environmentally-friendly renewable fuel, is a mixture of different fatty acid methyl esters produced by transesterification of vegetable oil triglycerides. Content of particular FAMEs is one of the qualities of biodiesel that is regulated (standard EN 14214). FAME composition of biodiesel depends upon the feedstock and its quality. In Serbia for production of biodiesel rapeseed and sunflower oil (SFO) are mostly used, although waste frying oil from household and restaurants is possible and economically more favorable feedstock. Since transesterification of triglycerides is catalyzed reaction, aim of this work was to investigate the influence of different catalysts on FAMEs yield. NaOCH3. NaOH and KOH with HCI were studied as the catalyst for reaction of transesterification. FAMEs mixtures derived by transesterification of refined and different waste frying SFO samples in the presence of mentioned catalysts were qualitatively and quantitatively analyzed using gas chromatograph coupled with mass spectrometer as a detector. Content of FAMEs was the highest both for refined and waste frying SFOs when KOH and HCI were used as catalyst for transesterification. The method which uses KOH and HCI as catalyst was the fastest among investigated methods. |
