Abstract
Procedimiento para la obtención de carbones activados mediante activación química con hidróxido sódico, hidróxido potásico o sus mezclas. El procedimiento comprende mezclar un precursor carbonoso con un agente activante seleccionado entre hidróxido sódico, hidróxido potásico y sus mezclas, mediante distintos métodos de mezclado (impregnación del precursor carbonoso con una disolución acuosa del agente activante, o alternativamente con la mínima cantidad necesaria de una disolución acuosa saturada, o cercana a la saturación, de dicho agente activante, para humectar todo el precursor carbonoso, y posterior adición de agente activante, en forma sólida), carbonizar el material resultante y lavarlo. Los carbones activados obtenidos tienen elevada microporosidad, distribución de porosidad controlada, buenas características de área superficial y capacidad de adsorción, y pueden utilizarse en múltiples aplicaciones que implican adsorción en fase gas, almacenamiento de gases y de energía en condensadores de doble capa (EDLC).
