    Abstract: The present invention is a gas separation method using a plurality of adsorption columns packed with an adsorbent. A cycle including a series of steps (adsorption, first pressure reduction, second pressure reduction, desorption, scrubbing, and repressurization) is repeated in each adsorption column. In the adsorption step, a gas mixture (G1) is introduced into a column (A) so as to cause the adsorbent to adsorb unnecessary components, and a product gas (G2) is led outside of the column (FIG. 3A). In the first pressure reduction step, the internal pressure of the column (A) is reduced by lead-out of a gas (G3) (FIG. 4A). In the second pressure reduction step, the internal pressure of the column (A) is further reduced by lead-out of the gas (FIG. 4B). In the desorption step, the unnecessary components are desorbed from the adsorbent and purged from the column (A) (FIG. 4C). In the scrubbing step, introduction of the gas (G3) and purging of the gas (G4) are performed simultaneously (FIG. 5A). In the repressurizing step, the internal pressure of the column (A) is raised by introducing the gas (G3) (FIG. 5B). The gas (G3) that is led out from the column (A) during the first pressure reduction step is introduced into the column (C) during the scrubbing step (FIG. 4A), and the gas (G3) that is led out from the column (A) during the second pressure reduction step is introduced into the column (C) during the repressurizing step (FIG. 4B).

    Abstract: A method is provided for separating hydrogen gas from a mixed gas obtained by autothermal reforming reaction of hydrocarbon-based material in which air is added. In this method, by pressure swing adsorption using adsorption towers (A-C) each filled with an adsorbent, a cycle is repeatedly performed, including an adsorption step of introducing the mixed gas into the adsorption tower to adsorb unnecessary gas contained in the mixed gas by the adsorbent to discharge product gas with high hydrogen gas concentration from the adsorption tower, and a desorption step of desorbing the unnecessary gas from the adsorbent to discharge the unnecessary gas from the adsorption tower. The adsorbent includes a 10 to 50% filling percentage of activated carbon-based first adsorbent (D) arranged in the adsorption tower at an upstream portion in the flow direction of the mixed gas and a 90 to 50% filling percentage of zeolite-based second adsorbent (E) arranged in the adsorption tower at a downstream portion in the flow direction.
