Abstract

SE DEPOSITA SOBRE UNA SOLERA MOVIL (5) UNA CARGA (7) COMPUESTA DE CAPAS SUPERPUESTAS DE MATERIA FINAMENTE DIVIDIDA, ESTANDO AL MENOS UNA DE ESTAS CAPAS CONSTITUIDA ESENCIALMENTE POR OXIDOS DE HIERRO (1) Y ESTANDO AL MENOS OTRA CAPA FORMADA POR UNA MEZCLA (M) DE UN AGENTE REDUCTOR CARBONADO SOLIDO (2) Y POR UN AGENTE DESULFURANTE (3). SE CALIENTA LA CARGA PARA PROVOCAR LA GASIFICACION AL MENOS PARCIAL DE LIBERACION DE COMPUESTOS GASEOSOS DEL CARBONO Y DEL AZUFRE. SE EFECTUA LA REDUCCION DE LOS OXIDOS DE HIERRO MEDIANTE AL MENOS UNA PARTE DEL MONOXIDO DE CARBONO (CO) CONTENIDO EN LOS COMPUESTOS GASEOSOS DEL CARBONO Y SE FIJA, MEDIANTE EL AGENTE DESULFURANTE, AL MENOS UNA PARTE DEL AZUFRE CONTENIDO EN LOS COMPUESTOS GASEOSOS DEL AZUFRE,. POR FIN, SE SEPARAN LOS OXIDOS DE HIERRO REDUCIDOS Y LA MATERIA QUE CONTIENE LOS RESIDUOS DEL AGENTE REDUCTOR CARBONADO SOLIDO Y EL AGENTE DESULFURANTE. LOS OXIDOS DE HIERRO PUEDE DEPOSITARSE BAJO LA FORMA DE PEQUEÑOS MONTONES SEPARADOS.
