Preparación y caracterización de carbones activados obtenidos a partir de la retama

Abstract

La retama negra (Sarothamnus scoparius) es un arbusto que crece en forma abundante en la región extremeña. En el presente estudio se investiga su posible utilización como material de partida en la preparación de carbón activado. Ésta se lleva a cabo por el método de activación física. Los carbones son caracterizados mediante análisis químico, adsorción de N2 a 77 K, porosimetría de mercurio y medida de densidades por desplazamiento de helio y de mercurio. Se ha constatado que activando en CO2 se preparan carbones activados que poseen unas mejores propiedades texturales que los obtenidos utilizando aire. Los efectos de la activación sobre las propiedades texturales de los carbones se favorecen con la subida de la temperatura de activación. .
