Lozada-Castro Ingeniería fat tallow biodiesel solid waste Pressurized solvent Tallow is produced in leather manufacturing, particularly in the fleshing stage. It contains large amounts of fat, which, in most industrial plants, pollutes water and soil due to poor disposal. In order to take advantage of this solid waste, chemical processes have been applied to transform the fats extracted from tallow into biodiesel. In this work, an extraction technique involving non-polar solvents pressurized at 15 psi. With gasoline, a 51,0% fat recovery was obtained. The quality of the extracted fat was determined by analyzing density, viscosity, melting point, moisture, acidity, and acidity, peroxides, saponification, and iodine indices. Biodiesel was obtained via transesterification reactions with methanol and sodium hydroxide. The content of methyl esters produced in the reaction was characterized by means of gas chromatography coupled with mass spectrometry, where the methyl esters of palmitic and oleic fatty acids were identified as major components. 2023 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379907004 https://www.redalyc.org/journal/643/64379907004/ https://www.redalyc.org/journal/643/64379907004/html/ https://www.redalyc.org/journal/643/64379907004/64379907004.epub https://www.redalyc.org/journal/643/64379907004/movil 10.15446/ing.investig.97254 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.1 Vol.43 |
