The present invention relates to a pressure swing adsorption (PSA) device for hydrogen purification and a hydrogen purification method using the same.n n n The hydrogen purification method using the pressure swing adsorption apparatus of the present invention comprises a plurality of adsorption towers connected to a raw material supply pipe, a hydrogen storage tank for collecting hydrogen purified from the adsorption towers, and a valve for opening and closing a plurality of pipes connected to the respective adsorption towers. In the pressure swing adsorption apparatus, the adsorption column is activated carbon and zeolite 13X, zeolite 5A and zeolite 5A which are capable of removing carbon dioxide and methane and carbon monoxide contained in the hydrogen mixed gas supplied through the raw material supply pipe therein. The adsorbent of the selective adsorbent is packed in a multi-layered structure, and the technical feature is to minimize the carbon monoxide content in the hydrogen discharged by being sequentially adsorbed in the adsorbent in the adsorption column, and lower the carbon monoxide content in the purified hydrogen product to 10 ppm or less Produce hydrogen products There is easy advantage.n n n n Hydrogen purification, adsorbent, carbon monoxide selective adsorbent, pressure swing adsorption |
