Abstract
La presente invención se refiere a mejoras en un método para producir carbón granular activado a partir de un carbón bituminoso de baja calidad en que el proceso comprende triturar el carbón para formar gránulos, tratar los gránulos mezclandolos con un ácido inorgánico en una atmósfera exenta de oxígeno a una temperatura mayor que la temperatura de carbonización y activar los gránulos desvolatilizados mediante un calentamiento a una atmósfera que contiene un agente activador gaseoso a una temperatura mayor que la temperatura de desvolatilización caracterizadas en que se hace uso de un carbón bituminoso fundible de baja calidad pro no de fácil coquificación con el fin de emplear un carbón de baja calidad aún cuando produciendo un carbón granular activado de dureza adecuada para mantener la integridad granular en uso repetido y su regeneración para formar los gránulos que se tratan por lixiviación con una solución acuosa dilúida de un ácido inorgánico durante un tiempo, una temperatura, una concentración de ácido y una relación de solución respecto a carbón suficientes, junto con la carbonización antes mencionada para evitar la fusión de los gránulos durante la desvolatilización subsiguiente al separar el ácido mediante su lavado, secándolos eficazmente y mezclándolos con un ligador carbonoso; se reducen los gránulos tratados para formar un polvo fino que se comprime y en seguida se reduce para formar los gránulos antes de la carbonización.
