Abstract

METODO PARA REACTIVAR UN CATALIZADOR E INSTALACION PARA REALIZAR EL PROCEDIMIENTO. CONSISTE EN IMPULSAR AL CATALIZADOR QUE TIENE REBAJADA SU ACTIVIDAD, EN ATMOSFERA REDUCTORA CON UNA CORRIENTE DE CO A 500JC, PARA HACER PENETRAR AL CO ENTRE LOS POROS DEL CATALIZADOR, ORIGINAR UN DEPORTILLAMIENTO EN ZONAS EXTERIORES DEL MISMO Y OBTENER ZONAS LIBRES ACTIVAS DEL CATALIZADOR. LA MATERIA PRIMA DE LOS CATALIZADORES ES PRODUCTO INTERMEDIO O PRODUCTOS DE DESECHO DE LA PRODUCCION DE ACERO COMO ESCORIAS DE HORNO ALTO QUE TIENE UNA SUMA EFECTIVA O SUMA PROPORCIONAL DE IONES FE2B, CR3 Y TI4B CON LA FASE MAS BAJA ESTABLE EN UNA OXIDACION DEL 3%. CONSTA DE: UN REACTOR DOBLE (3) CON 2 CAMARAS (1, 2) EN DONDE SE COLOCA EL CATALIZADOR; UN CONDUCTO ALIMENTADOR DE GAS (5).
