To provide an adsorption column for a pressure fluctuation adsorption device for manufacturing hydrogen which is capable of reducing the consumption of a high-purity hydrogen to be used for regenerating an adsorbent and upgrade the recovery of the high-purity hydrogen and such other advantages that the fill of zeolite can be curtailed and the height of the adsorption column can be decreased consequently and also its capacity can be diminished.
In the pressure fluctuation adsorption device for manufacturing a high-purity refined hydrogen through adsorbing/removing an impurity gas from a gas containing hydrogen, an adsorbent bed comprising an active carbon layer, a carbon monoxide adsorbent layer and a zeolite layer formed in a laminar fashion, is provided in the adsorption column for the device.
