METHOD OF TREATING MATERIAL IN A FLUIDIZED BED REACTOR

摘要

A method or treating materials in a fluidized bed reactor, wherein the material to be treated is brought into contact with hot particles removed from the flue gases coming from the fluidized bad reactor to bring about chemical and/or thermal reactions in the material before it is introduced into the fluidized bed reactor together with recycled particles. Useful components can be recovered in the form of gases, solids or liquids in connection with this treatment.
