摘要： This invention relates to a process for reducing solids containing iron oxide, such as iron ore, in which fine-grained solids are heated and at least partly calcined in a pre heating stage (2, 9). In a first fluidized-bed reactor (14) downstream of the preheating stage (2, 9), the solids are prereduced and reduced further in a second fluidized-bed reactor (16). Downstream of the second reactor (16) a briquetting stage (20) is pro vided, in which the solids are briquetted at a temperature above 500°C To increase the energy efficiency of the process and improve the flowability of the solids in the briquetting stage (20), magnesite is added to the preheating stage (2, 9) together with the solids containing iron oxide, which magnesite is at least partly calcined in the preheating stage (2, 9) to obtain magnesium oxide. Furthermore, the invention relates to a corresponding plant.

摘要： Man gibt körnige Kohle und vorgewärmtes körniges Eisenerz einem Schwelreaktor auf, in welchem durch Zufuhr von sauerstoffhaltigem Gas und durch partielle Oxidation der Bestandteile der Kohle Temperaturen im Bereich von 800 bis 1050 °C erzeugt werden. Im Schwelreaktor hält man die körnigen Feststoffe in wirbelnder Bewegung. Aus dem oberen Bereich des Reaktors führt man heisses Abgas zu einem Festoff-Abscheider. Das körnige Eisenerz wird mit dem heissen Abgas vorgewärmt und heisses, körniges Gemisch aus Eisenerz und Schwelkoks wird als Produkt aus dem Reaktor und/oder aus dem Abscheider abgezogen. Der Schwelreaktor kann als Wirbelschichtreaktor oder als pneumatische Förderstecke ausgebildet sein. Das körnige Gemisch aus Eisenerz und Schwelkoks ist z.B. für einen Schmelzreduktionsprozess geeignet.

摘要： This invention relates to a process for producing metal oxide from metal hydroxide, in which the preheated metal hydroxide is at least partly supplied via at least one pneumatic delivery conduit and via at least one downstream separating cyclone (8, 11) to a fluidized-bed reactor (12), where it is heated to a temperature of 650 to 1250°C by combustion of fuel, and metal oxide is produced. In a mixing vessel (19), the metal oxide is mixed with a partial stream of preheated metal hydroxide such that the preheated metal hydroxide is further heated and at least partly calcined. Then, the metal oxide is supplied from the mixing vessel (19) to at least one cooling stage (27, 28, 30, 31). The energy utilization of the process is increased in that the waste gas of the at least one separating cyclone (8, 11) is introduced into the mixing vessel (19) as conveying air such that the metal oxide from the mixing vessel (19) is pneumatically delivered into the at least one cooling stage or a de livery conduit (24) leading to the same. Furthermore, the invention relates to a corresponding plant.
