NOVELTY - A sorption enhanced steam methane reforming reaction device comprises a mixer (1), a grilling type fluid bed reactor (2) installed at an outlet of the mixer, a cyclone separator (3), a regenerating reactor (4), and two material seals (4a, 4b). The outlet of the reactor is connected with the cyclone separator. The outlet of the cyclone separator is connected with the regenerating reactor via the first material seal. The outlet of the regenerating reactor is connected with the mixer via the second material seal.    USE - A sorption enhanced steam methane reforming reaction device for producing hydrogen (claimed).    ADVANTAGE - The reaction avoids the material wastage and energy wastage caused by the repeated oxidation and reduction of the catalyst. Only the adsorbent is carried by the reactive gas to pass through the grilling type fluid bed reactor. The reaction device can operate continuously.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sorption enhanced steam methane reforming reaction for producing hydrogen, comprising contacting and reacting with catalyst coating on grilling, where water steam and methane are in the mole ratio of 2-6. The reactor outlet and inlet are at 450-850 degrees C and 440-840 degrees C. The operation pressure is 0.3-4 MPa. The gas and solid mixture is placed in the cyclone separator to separate. The regenerated adsorbent is put in the mixer. Carbon is removed from the system with air. The regenerating reactor is kept at 600-950 degrees C. Compensating and removing equal fresh adsorbent to the mixer can be performed at 450-850 degrees C. The adsorbent is carried by steam and methane to enter the grilling type fluid bed reactor to be subject to the next sorption enhanced steam methane reforming reaction.
