1. A method of operating an adsorption apparatus configured to adsorb an adsorption target component in a gas to be treated through use of a physical adsorbent,
wherein the adsorption apparatus includes a plurality of adsorption beds each packed with the physical adsorbent, each of the plurality of adsorption beds being configured to be switchable between a part of adsorption beds to which the gas to be treated is supplied so that an adsorption step of adsorbing the adsorption target component is performed, and another adsorption bed in which a regeneration step of desorbing the adsorption target component to regenerate the physical adsorbent is performed,
wherein the regeneration step includes:
a desorption step of heating the physical adsorbent to desorb the adsorption target component;
a cooling step of subsequently causing a gas for cooling to flow through the another adsorption bed so as to cool the physical adsorbent having a temperature increased in the desorption step, to thereby cool the another adsorption bed until an outlet temperature of the another adsorption bed reaches a temperature set in advance; and
a standby step of thereafter standing by for switching to the adsorption step, and
wherein the standby step includes causing a gas for standby for maintaining a cooled state to flow through the another adsorption bed cooled in the cooling step, and
wherein the gas for standby is the gas to be treated.
