Disclosed are a fluidized bed water gas shift membrane reactor and a method for separating carbon dioxide using the same. More specifically, disclosed are a fluidized bed water gas shift membrane reactor provided on the back of a gasification reactor to produce a synthetic gas consisting of hydrogen and carbon monoxide by reaction of a solid hydrocarbon with water or oxygen, wherein the carbon monoxide present in an amount of 40 to 70 vol % in the synthesis gas reacts with steam in the presence of a catalyst to produce a mix gas of hydrogen and carbon dioxide, and the hydrogen is selectively isolated from the mix gas through a Pb&#x2014;Cu shift membrane to increase the concentration of carbon dioxide present in the mix gas and separate the carbon dioxide, and a method for separating carbon dioxide using the same.

Disclosed are a multi water-gas shift membrane reactor for producing high-concentration hydrogen and a method for producing hydrogen using the same. More specifically, disclosed are a multi water-gas shift membrane reactor wherein high-concentration carbon monoxide, obtained by dry-gasification performed by reacting dry bituminous coal with water and oxygen, reacts with water gas in the presence of catalysts in a single reactor, to produce hydrogen and carbon dioxide and separate highly pure hydrogen and carbon dioxide through a separation membrane arranged in a low region, and a method for producing hydrogen.

Multi water-gas shift membrane reactor for producing high concentration hydrogen and method for producing hydrogen using the same

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&#xb0; C., may be favorably converted into hydrogen without mixing both of the catalysts.
