Abstract:
1. A pressure swing adsorption apparatus, comprising 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 respectively connected to the adsorption columns, wherein 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 water, carbon dioxide, methane, and carbon monoxide from a hydrogen-containing gas mixture supplied through the feed supply pipe, and a content of carbon monoxide in hydrogen that is discharged is minimized through sequential adsorption on the adsorbents in the adsorption columns.
