Resumen
[ES]En este trabajo se ha estudiado la conversión a biodiésel de aceite comercial de girasol refinado mediante la reacción de transesterificación alcalina ya que es el proceso comercial más empleado. Se ha empleado metodología de experimentos analizando y optimizando resultados con el software Desing- Expert estudiando la influencia de la temperatura, tiempo de reacción y exceso de metanol con respecto del teórico y como respuesta, para su evaluación, se ha calculado el rendimiento de reacción de biodiésel (referido como porcentaje del máximo teórico alcanzable). Además de la producción de biodiésel, se le ha realizado al producto final un control de calidad normalizado. Se llevó a cabo la medida de densidad y viscosidad según la norma (UNE En 14214). También se ha introducido un análisis por simulación con el software Aspen Plus del proceso de tranesterificación y recuperación de metanol con el propósito de comparar ambos escenarios.
[EN]In this work the conversion of a commercial oil biodiesel of refined sunflower by means of the reaction of alkaline transesterification and that is the most used commercial process has been studied. Experimenting with the influence of temperature, reaction time and excess methanol on the theoretical and as a response, for its evaluation, has calculated the yield of the Biodiesel reaction (referred to as percentage of the theoretical attainable maximum). In addition to the production of biodiesel, a standard quality control end product has been produced. The density and viscosity measurement was carried out according to the standard (UNE EN 14214). A simulation analysis with the Aspen Plus software of the process of transfer and recovery of methanol has also been introduced in order to compare both scenarios.
