In this research, the possibility of using Ca(OH) 2 in the form of commercial hydrated lime as a catalyst for the methanolysis of refined rapeseed oil was evaluated. Characterization of unused catalyst was performed by SEM-EDS, laser diffraction, XRF, BET, XRD and TG/DTG methods, and vegetable oil was analyzed for physicochemical characteristics. W...

... biodiesel is a mixture of fatty acid esters, and taking the general assumption that the existing fatty acid profiles of the feedstock remain unchanged after transesterification [48], it follows that the properties of biodiesel largely depend on the fatty acid profile of starting material. The results of gas chromatography of rapeseed oil (Table 3) show the dominant content of four fatty acids (oleic, linoleic, linolenic and palmitic). From the aspect of desirable profile of fatty acids in raw materials for biodiesel production, given the influence of their methyl esters on fuel properties, high presence of monounsaturated fatty acids (such as oleic and palmitoleic acid), reduced presence of polyunsaturated, and controlled content of saturated fatty acids are recommended [49]. ...Similar publications
This study presents a brief overview of the composition and properties of various oils used in biodiesel production and the alkali, acidic and enzymatic transesterification reactions used in production. Nowadays, vegetable and microalgae oils are mostly used in biodiesel production. Recently, however, animal fats, processed oils, industrial oils an...
