Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA REGENERACION DE ADSORBENTES ORGANICOS UTILIZADOS, COMO TIERRA DESCOLORANTE O ADSORBENTES PRODUCIDOS SINTETICAMENTE Y/O MEZCLAS DE TIERRA DESCOLORANTE/CARBONO ACTIVO, DONDE LOS RESIDUOS QUE CONTIENEN CARBONO QUE ESTAN ADHERIDOS A LOS ABSORBENTES SE OXIDAN POR TRATAMIENTO TERMICO EN UN LECHO FLUIDIZADO QUE CONTIENE UN MATERIAL GRANULAR INERTE A UNAS TEMPERATURAS INFERIORES A 1000 (GRADOS) C, ELIMINANDOSE DEL ABSORBENTE, DE FORMA QUE EL ADSORBENTE REGENERADO SE SEPARA DEL MATERIAL GRANULAR INERTE; EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA TEMPERATURA EN EL LECHO FLUIDIZADO SE AJUSTA A UNA TEMPERATURA DE APROXIMADAMENTE 600 A 700 (GRADOS) C Y LA TEMPERATURA EN EL VOLUMEN DE GAS LIBRE SE AJUSTA A UNA TEMPERATURA QUE NO SOBREPASE LA DEL LECHO FLUIDIZADO.
