Síntesis y caracterización de nanopartículas de Fe2O3 para la producción de biodiésel
Resumen
En este trabajo, se elaboraron y caracterizaron nanopartículas metálicas de hematita (α-Fe2O3) sintetizadas por el método tradicional de coprecipitación seguido de un tratamiento térmico a 500 °C durante 1 hora a atmosfera ambiente, para ser empleadas como catalizador heterogéneo para la producción de biodiésel a partir del aceite de soya. Las propiedades texturales (BET) y morfológicas (SEM) de las nanopartículas indican que presentan un área superficial de 100.86 m2/g y una morfología superficial en forma de nanovarillas con abundante porosidad. El análisis XRD indico los planos (1 0 4) y (1 1 0) característicos de las nanopartículas de α-Fe2O3. El rendimiento máximo que alcanzó en la producción de biodiésel fue del 90 % bajo condiciones optimizadas. Una relación molar de metanol a aceite de soya de 15:1, con una carga de catalizador del 4 wt %, y un tiempo de reacción de 240 min. La temperatura de reacción y la agitación fueron de 65 °C y 600 rpm. El catalizador basado en nanopartículas metálicas de α-Fe2O3 puede ser reutilizado durante 7 ciclos consecutivos hasta perder su actividad catalítica. El biodiésel producido de soya cumple con los valores establecidos por la Sociedad Americana de Pruebas y Materiales (ASTM)
