    Abstract: A pressure swing adsorption apparatus is provided to produce hydrogen product of high purity by improving adsorptive selectivity relative to impurities in a mixed gas comprising hydrogen gas through a three column type or four column type pressure swing adsorption apparatus, thereby lowering carbon monoxide(CO) and carbon dioxide(CO2) components to extremely low contents. In a pressure swing adsorption apparatus(100) comprising a plurality of adsorption columns(111-114) connected to a raw material supply pipe, a hydrogen storage tank(130) collecting hydrogen purified in the adsorption columns, and valves opening or closing a plurality of pipes connected to the respective adsorption columns, the pressure swing adsorption apparatus is characterized in that: adsorbents including activated alumina or silica gel, activated carbon, zeolite 13X, zeolite 5A, and a carbon monoxide selective adsorbent except the zeolite 5A, which are capable of removing water, carbon dioxide, methane, and carbon monoxide included in a hydrogen mixed gas supplied through the raw material supply pipe are charged into the adsorption columns in a multi-layer structure, and the content of carbon monoxide in hydrogen exhausted after being sequentially adsorbed onto the adsorbents in the adsorption columns is minimized.
