Transesterificación de aceites vegetales empleando catalizadores heterogéneos

Abstract

El progresivo aumento en los precios del petroleo y el agotamiento de sus reservas ha motivado a la sociedadcientifica a pensar en combustibles alternativos y renovables como el biodiesel. La produccion de biodiesel selleva a cabo principalmente por transesterificacion de triacilgliceridos (aceites vegetales y grasas animales) y unalcohol liviano en presencia de catalizadores. Los catalizadores homogeneos tipo hidroxidos de sodio o de potasioson tipicamente los mas empleados en la produccion de biodiesel; desafortunadamente problemas asociadosprincipalmente con el aumento de costos debido a la implementacion de etapas de separacion y el tratamientoposterior de aguas residuales, ha enfocado la atencion de los investigadores hacia el empleo de catalizadores heterogeneos.Este articulo presenta una revision sobre tres tipos de catalizadores heterogeneos, los oxidos de metalesalcalinoterreos, las zeolitas y los heteropoliacidos, empleados en reacciones de transestrificacion de aceites parala obtencion de biodiesel. En terminos generales, estos catalizadores han demostrado ser eficientes, selectivos, facilesde separar, reutilizables y algunos mas que otros, tolerables a la presencia de agua y de acidos grasos libres.
