Abstract
A method of concentrating ozone gas including: causing ozone gas contained in ozone-oxygen mixture gas to be selectively adsorbed to adsorbents which are filled in a non-cooled state in at least two adsorbing cylinders arranged parallel to one another; desorbing the ozone gas from the adsorbents by subjecting a depressurizing process to each adsorbing cylinder during an ozone gas desorption operation; repeating an adsorption step and a desorption step alternately in the at least two adsorbing cylinders; and controlling the adsorbing cylinders, in such a way that one of the adsorbing cylinders is performing the adsorption step while another one of the adsorbing cylinders is performing the desorption step.
