Abstract：
 This invention relates to a method for producing hydrogen by using combustible reducing gas as raw material, and using iron/ferrous oxide as oxygen-carrier, during the reaction in a fluidized bed reactor, with coproduct of high concentration carbon dioxide. This invented equipment comprises: a circulation fluidized bed, a moveable bed, a bubbling fluidized bed, a hydrogen separator unit and a carbon dioxide separator. A horn type bucket is used under the bottom of hydrogen separator and connecting the lower part of the bubbling fluidized bed; the bottom of the carbon dioxide separator is connected with horn type bucket; a contraction type bucket is used for connection middle lower part of the bubbling fluidized bed and the moveable bed; the upper part of moveable bed is connected with the middle part of the circulation fluidized bed; the lower ends of the circulation fluidized bed and moveable bed and bubbling fluidized bed are equipped with fluidized steam inlets A and B gas fuel inlet C. This invention has advantages of: simple struction, low cost and high efficiency.
