Zusammenfassung: | The invention discloses a method for dehydrogenating high-concentration carbon monoxide gas, which comprises the following steps: setting at least two catalytic converters, at least one activated converter is called as a working tower, feeding raw material gas containing less than or equal to 1% of hydrogen, more than or equal to 99% of carbon monoxide and more than or equal to 0.3 MPa, and filling an activated composite catalyst in the working tower, the reaction of the composite catalyst is a combination of a Fischer-Tropsch catalyst, a shift catalyst and a carbon dioxide absorption catalyst; the hydrogen is converted by the composite catalyst to react with the carbon monoxide into hydrocarbons, alcohols, ethers and carbonates, the pressure is greater than or equal to 0.25 MPa, the hydrogen is called dehydrogenated gas when the concentration of the hydrogen is reduced to be less than 50ppm, and the dehydrogenated gas is sent to a pressure swing adsorption device to purify the carbon monoxide, so that the co |
