El-Dekhaila iron Co. a importé les pellets de l'extérieur de l'Egypte, pendant le transport de l'extérieur à l'entreprise, beaucoup de fines (fines de pellets de déchets) se sont formées, ces fines n'étaient pas appropriées pour la réduction à l'intérieur du four de réduction. L'hydrogène s'est avéré être un bon agent réducteur ainsi qu'un matériau respectueux de l'environnement. Ce livre a été réalisé pour se concentrer sur la production de déchets d'oxyde de fer El-Dekhaila sous différentes formes (briquettes et boulettes) et les réduire à l'aide d'hydrogène dans...

Während des Transports von außerhalb zum Unternehmen bildete sich viel Feinstaub (feiner Pelletabfall), der für die Reduktion im Reduktionsofen nicht geeignet war. Wasserstoff ist nachweislich ein gutes Reduktionsmittel und ein umweltfreundliches Material. In diesem Buch ging es um die Herstellung von El-Dekhaila-Eisenoxidabfällen in verschiedenen Formen (Briketts und Pellets) und deren Reduktion mit Wasserstoff im Temperaturbereich von 700 bis 950 oC. Bei der Untersuchung der Reduktionskinetik wurde das...
