Abstract

ABSORBENTES DE LARGA DURACION QUE CONTIENEN OXIDO DE ZINC PARA DESULFURACION DE GAS DE HULLA. SE ELABORAN PASTILLAS ABSORBENTES DE LARGA DURACION QUE CONTIENEN OXIDO DE CINC PARA ELIMINAR SULFURO DE HIDROGENO DE UNA CORRIENTE DE GAS A UNA TEMPERATURA ELEVADA PARA CONTENER TITANIA COMO DILUYENTE, GEL DE SILICE DE ALTA SUPERFICIE ESPECIFICA COMO MATERIAL DE MATRIZ, Y UN AGLOMERANTE. ESTOS MATERIALES SE MEZCLAN, SE HUMEDECEN, Y SE FORMAN EN PASTILLAS, QUE A CONTINUACION SE SECAN Y SE CALCINAN. LAS PASTILLAS RESULTANTES SUFREN CICLOS REPETIDOS DE SULFURACION Y REGENERACION SIN PERDIDA DE REACTIVIDAD Y SIN DEGRADACION MECANICA. LA REGENERACION DE LAS PASTILLAS SE LLEVA A CABO PONIENDO EN CONTACTO EL LECHO CON UNA MEZCLA DE GASES OXIDANTES.
