Abstract: PURPOSE: A process of pressure swing absorption of hydrogen is provided which improves the productivity of pressure swing absorption process of purifying hydrogen with high purity from the hydrogen containing mixed gas containing CO2, CH4, CO, hydrocarbon and the like. CONSTITUTION: A process of pressure swing absorption of hydrogen comprises steps of: (i) an absorption step of removing impurities from high pressure raw material gas supplied to an absorption tank and obtaining product hydrogen with high purity from a tank outlet; (ii) a partial pressure homogenization step of supplying the exhausted hydrogen to another absorption tank with decompressing the absorption finished tank in parallel to the flow of the raw material gas; (iii) a washing supply step of further decompressing the partial pressure homogenization step finished absorption tank and supplying the exhausted gas to washing gas of an absorption tank in the washing step; (iv) a permanent current flow decompressing step of decompressing the absorption tank at an atmospheric pressure with a permanent current to further remove the impurities absorbed at the absorption tank after finishing the washing supply step; (v) a washing step of removing absorbed impurities by introducing gas exhausted from another tank in the washing supply step; (vi) a partial pressure homogenization step of pressurizing the tank by introducing the gas exhausted from the another absorption tank in the partial pressure homogenization step through the outlet portion of the tank with a permanent current; and (vii) a product gas pressurizing step of pressurizing the pressure of the absorption tank by introducing a part of the product hydrogen which has finished the partial homogenization step with a permanent current.
