摘要： The present invention relates to a method for operating a fluidized bed apparatus and to a fluidized bed apparatus, the method comprising the following steps: providing particulate metal to a reaction chamber of a fluidized bed reactor, providing an oxidizing agent to a fluidizing bottom of the fluidized bed reactor such that particulate matter comprising the particulate metal is fluidized, wherein the particulate metal reacts with the oxidizing agent to particulate metal oxide, withdrawing particulate metal oxide from the reaction chamber, storing the withdrawn particulate metal oxide, providing particulate metal oxide to the reaction chamber of the fluidized bed reactor, providing a reducing agent containing gas to the fluidizing bottom of the fluidized bed reactor such that particulate matter comprising the particulate metal oxide is fluidized, wherein the particulate metal oxide reacts with the reducing agent to particulate metal, withdrawing the particulate metal from the reaction chamber, storing the withdrawn particulate metal.
