| description |
Problems arising between biofuels and food as raw materials have led to investigating the use of inedible raw materials for their production. This work was aimed at studying the effect of temperature on converting castor oil in biodiesel production. Oil transesterification with methanol was carried out using an alkaline catalyst (0.5% NaOH - water solution) for 1 hour using a 6:1 alcohol/oil molar ratio, at atmospheric pressure and taking temperature as a free variable. The temperature was evaluated at 68°F, 86°F, 104°F and 122ºF. The reaction products were analyzed by gas chromatography (CG-FID) for quantifying the fatty acid methyl esters (FAME) present. The results showed different dispersion depending on temperature, finding that 122°F resulted in less dispersion than the others. CG-FID analysis showed that most FAME content was reached at 122ºF, such temperature giving the highest ricinoleic acid conversion rate. Gas chromatography also revealed that reaction time was adequate, in process conditions, for obtaining ricinoleic acid-based 94.26% con- version. |

Este trabajo busca estudiar el efecto que tiene la temperatura sobre la conversión en la producción de biodiesel usando aceite de higuerilla. La transesterificación del aceite con metanol se realiza vía catálisis básica (0,5 % de NaOH) en un tiempo de 1 hora, usando una relación molar 6:1 de alcohol/aceite, bajo presión atmosférica, y dejando como variable libre la temperatura, a la cual se le asignaron los valores de 20, 30, 40 y 50 °C, llevando a cabo una ré- plica para cada valor. Los productos de reacción se analiza- ron mediante cromatografía de gases (CG-FID) para cuantificar la presencia de FAME (metil ésteres de ácidos grasos). Los resultados presentaron dispersiones diferentes dependiendo de la temperatura, encontrando la menor dispersión con el biodiesel obtenido a 50 °C. El análisis por cromatografía de gases demuestra que el contenido de FAME de mayor proporción se alcanza en las muestras de 50 °C, temperatura a la cual fue mayor la conversión del ácido ricinoleico (el de mayor presencia en el aceite de Higuerilla). La cromatografía también revela que el tiempo de reacción es el adecuado, a las condiciones de proceso establecidas, para lograr una conversión del 94,26% basada en el ácido ricinoleico.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/15733Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 30, núm. 2 (2010); 52-61 Ingeniería e Investigación; Vol. 30, núm. 2 (2010); 52-61 2248-8723 0120-5609Guerrero Fajardo, Carlos Alberto and Osorio León, Iván David and Sierra Vargas, Fabio Emiro (2010) Evaluating the effect of temperature on biodiesel production from castor oil.
