Abstract
A multi-fluidized bed water-gas shift reactor wherein a specific syngas containing a high concentration of carbon monoxide produced by gasification of a heavy carbon source such as coal, vacuum residue, glycerin, etc., is in contact with water under a catalyst so as to produce hydrogen and, in addition, a method for production of hydrogen using the foregoing reactor are disclosed. In other words, the disclosure describes a multi-fluidized bed water-gas shift reactor containing low and high temperature catalysts as well as steam and a method for production of hydrogen using the same, wherein 30 to 70% carbon monoxide in the syngas as a gas mixture containing hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, hydrogen monoxide, and the like, which are generated through partial oxidation and vapor gasification at 900 to 1,600° C., may be favorably converted into hydrogen without mixing both of the catalysts.
