Abstract

UN PROCESO PARA LA ELIMINACION DE FLUORURO DE UN CATALIZADOR DE FLUORACION AGOTADO, BASADO EN CROMO, PONIENDO EN CONTACTO EL CATALIZADOR CON HIDROXIDO DE POTASIO PARA PRODUCIR UNA SUSPENSION DE OXIDO DE CROMO HIDRATADO SOLIDO EN FLUORURO DE POTASIO ACUOSO. EL OXIDO DE CROMO HIDRATADO SOLIDO PUEDE SER SEPARADO DE LA SOLUCION, LAVADO CON AGUA Y/O ACIDO ACUOSO, Y PUESTO EN CONTACTO CON ACIDO NITRICO PARA PRODUCIR UNA SOLUCION DE NITRATO DE CROMO (III) DE LA CUAL PUEDE SER PREPARADO UN CATALIZADOR BASADO EN CROMO POR PRECIPITACION DE OXIDO DE CROMO HIDRATADO DESDE ELLA CON BASE ACUOSA, Y LAVADO, SECADO Y CALCINADO DEL OXIDO DE CROMO HIDRATADO.
