Abstract
A mixed gas is contacted with a non-carbonaceous adsorbent while irradiating the adsorbent with an electromagnetic wave having a frequency of 1 MHz to 25 GHz, such as a microwave, so that a gas component having a smaller coefficient of dielectric loss is selectively adsorbed by the adsorbent. A gas adsorbed on an adsorbent may be desorbed therefrom by contact with a desorbing gas while irradiating the adsorbent with the above electromagnetic wave.
