    摘要: A process for concentrating ozone, which includes switching a plurality of adsorption columns each packed with an adsorbent capable of preferentially adsorbing ozone thereon sequentially to an adsorption step where the adsorbent is maintained at a low temperature to adsorb ozone thereon; a desorption step where the adsorbent is heated to desorb ozone therefrom, and a scavenger gas is introduced in a substantially fixed amount into the adsorption column to discharge the thus desorbed ozone being carried on the scavenger gas; and a cooling step where the adsorbent having completed the desorption step is cooled to the same low temperature level as in the adsorption step. Heating of the adsorbent in the desorption step is carried out depending on the time elapsed after desorption is started or on the ozone concentration of the gas discharged from the adsorption column performing the desorption step. A gas having a predetermined pressure is employed as the scavenger gas in the desorption step. The adsorption step is divided into two steps: a pre-adsorption sub-step and a main adsorption sub-step. A low-temperature oxygen is employed as a cooling source in the cooling step and then supplied as a raw material of ozone to the ozonizer.
