Condición: Hervorragend. Zustand: Hervorragend | Seiten: 52 | Sprache: Französisch | Produktart: Bücher | 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 la plage de température de 700 à 950 oC. Dans l'étude de la cinétique de réduction, le modèle le plus satisfaisant a consisté à prendre la pente de la région linéaire initiale de la courbe de réduction fractionnelle en fonction du temps comme mesure de la constante de vitesse (k). Dans les tracés de k en fonction de 1/T, il y avait une ligne droite à partir de laquelle l'énergie d'activation a été calculée.…

Condición: Hervorragend. Zustand: Hervorragend | Seiten: 52 | Sprache: Italienisch | Produktart: Bücher | La El-Dekhaila iron Co. ha importato i pellet dall'esterno dell'Egitto; durante il trasporto dall'esterno all'azienda, si sono formati molti fini (pellet di scarto fini), che non erano adatti alla riduzione all'interno del forno di riduzione. È stato dimostrato che l'idrogeno è un buon agente riduttivo e un materiale ecologico. Questo lavoro è stato condotto per concentrarsi sulla produzione di rifiuti di ossido di ferro di El-Dekhaila in diverse forme (bricchette e pellet) e sulla loro riduzione con l'idrogeno in un intervallo di temperatura compreso tra 700 e 950 oC. Nello studio della cinetica di riduzione, il modello più soddisfacente è stato quello di prendere la pendenza della regione lineare iniziale della curva di riduzione frazionaria rispetto al tempo come misura della costante di velocità (k). I grafici di k vs. 1/T erano rettilinei da cui è stata calcolata l'energia di attivazione.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -El-Dekhaila iron Co. imported the pellets from the outside of Egypt, during the transportation from outside to Company, lot of fine (waste pellets fine) formed, this fine was not suitable for the reduction inside the furnace of reduction. Hydrogen has been proven to be a good reductive agent as well as an environment-friendly material. This book was conducted to focus on production of El-Dekhaila iron oxide waste in different forms (briquette and pellets) and reduced it by hydrogen in the temperature range 700 to 950 oC. In reduction kinetics study the most satisfactory model was done to take the slope of the initial linear region of fractional reduction vs. time curve as a measure of rate constant (k). In k vs. 1/T plots were straight line from which Activation Energy was calculated. 52 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El-Dekhaila iron Co. importó los pellets del exterior de Egipto, durante el transporte del exterior a la empresa, se formó mucho fino (fino de pellets de residuos), este fino no era adecuado para la reducción dentro del horno de reducción. Se ha demostrado que el hidrógeno es un buen agente reductor, así como un material respetuoso con el medio ambiente. Este libro se llevó a cabo para centrarse en la producción de residuos de óxido de hierro El-Dekhaila en diferentes formas (briqueta y pellets) y reducido por el hidrógeno en el rango de temperatura de 700 a 950 oC. En el estudio de la cinética de reducción, el modelo más satisfactorio fue tomar la pendiente de la región lineal inicial de la curva de reducción fraccionada vs. tiempo como medida de la constante de velocidad (k). En las gráficas k vs. 1/T se obtuvieron líneas rectas a partir de las cuales se calculó la energía de activación.…
