Abstract:
An ozone storage/recovery method comprising: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 having a SiO.sub.2 /Al.sub.2 O.sub.3 ratio of 70 to 100, a dealumination faujasite having a SiO.sub.2 /Al.sub.2 O.sub.3 ratio of about 20 to 400 and a mesoporous silicate, causing the adsorbent to adsorb ozone at a temperature of 0.degree. C. or below, and storing the ozone; anda process for desorbing the ozone adsorbed by the adsorbent in said ozone adsorbent tank and recovering the ozone from said adsorbent tank.
