Abstract

L'invention concerne un procédé pour la réduction de matière oxydée. Il comprend les étapes suivantes : - production d'un gaz réducteur contenant principalement du monoxyde de carbone et de l'hydrogène, à partir d'une matière de départ carbonée et/ou hydrocarbonée; - établissement du gaz réducteur ainsi produit à une température appropriée pour le procédé de réduction suivant et ensuite introduction du gaz dans un four à cuve (1) contenant la matière oxydée devant etre réduite; - élimination d'essentiellement toute l'eau et des particules du type poussières du gaz réducteur; -évacuation d'au moins une partie de l'écoulement de gaz de retour ainsi traité.The invention relates to a process for the reduction of oxidized material. It comprises the following stages: - production of a reducing gas containing mainly carbon monoxide and hydrogen, from a carbonaceous and / or hydrocarbon starting material; - establishment of the reducing gas thus produced at a temperature suitable for the following reduction process and then introduction of the gas into a tank furnace (1) containing the oxidized material to be reduced; - elimination of essentially all the water and dust-like particles from the reducing gas; evacuation of at least part of the return gas flow thus treated.
