Abstract
A method of 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 bed 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 may be recovered in the form of gases, solids or liquids in connection with this treatment.
