CA 2466495

The invention relates to a method for treating a fine-particled feedstock especially containing metal, wherein the feedstock and a treatment gas, especially a reduction gas, are introduced into a fluidized bed chamber (1), e.g. a fluidized bed reactor, in order to form a fluidized bed. The treatment gas is discharged from the fluidized bed after an at least partial reaction in the fluidized bed (4) and is subsequently partially utilized, preferably oxidated, outside the fluidized bed by means of an especially exothermic, chemical reaction with a reactive agent, preferably with a gaseous and/or liquid oxidizing agent. The thermal energy of said reaction is at least partially introduced into the fluidized bed chamber, especially into the fluidized bed or discharged therefrom. The invention also relates to a unit for operating a fluidized bed.

L'invention concerne un procédé pour le traitement d'une charge sous forme de fines particules, notamment métallifère. Pour former un lit fluidisé, ladite charge ainsi qu'un gaz de traitement, en particulier un gaz réducteur, sont introduits dans une chambre à lit fluidisé (1), par exemple dans un réacteur à lit fluidisé. Après réagi au moins partiellement dans le lit fluidisé (4), le gaz de traitement est alors évacué dudit lit fluidisé, puis au moins partiellement valorisé, de préférence oxydé, à l'extérieur dudit lit fluidisé par réaction chimique, notamment exothermique, avec un agent réactif, de préférence un oxydant gazeux et/ou liquide. L'énergie thermique de ladite réaction est introduite au moins partiellement dans la chambre à lit fluidisé, en particulier dans le lit fluidisé, ou évacuée de celle-ci. L'invention concerne de plus un ensemble conçu pour le fonctionnement d'un lit fluidisé.
