Abstract
An ozone storage/recovery method comprises a process for supplying an ozone-containing gas, generated by an ozone generator, to an ozone adsorbent tank filled with an ozone adsorbent contained at least one high-silica material selected from the group consisting of a high-silica pentasil zeolite, a dealumination faujasite and a mesoporous silicate, causing the adsorbent to adsorb ozone at a temperature of 0.degree. C. or below, and storing the ozone, and a process for desorbing the ozone adsorbed by the adsorbent in the ozone adsorbent tank and recovering the ozone from the adsorbent tank, whereby ozone can be supplied as required.
