Abstract
Disclosed are a pressure swing adsorption apparatus for hydrogen purification and a hydrogen purification method using the same. The pressure swing adsorption apparatus for hydrogen purification includes a plurality of adsorption columns connected with a feed supply pipe, a hydrogen storage tank for collecting purified hydrogen from the adsorption columns, and valves for opening or closing a plurality of pipes connected to the respective adsorption columns, and the adsorption columns are packed with adsorbent beds of active alumina or silica gel, activated carbon, zeolite 13X, zeolite 5A, and a carbon monoxide-selective adsorbent other than the zeolite 5A, in order to remove carbon dioxide, methane, and carbon monoxide from a hydrogen-containing gas mixture supplied through the feed supply pipe, and the content of carbon monoxide in the discharged hydrogen is minimized through sequential adsorption on the adsorbents in the adsorption columns. The content of carbon monoxide in the purified hydrogen product can be decreased to 10 ppm or less, thus facilitating the production of highly pure hydrogen products.
