Abstract

An apparatus for manufacturing high concentration ozone gas, characterized by employing a pressure swing adsorbing apparatus having a plurality of adsorbing layers filled with ozone adsorbent, in which the ozone adsorbent is one or two or more kinds of adsorbent selected from the group consisting of high silica pentasyl zeolite, dealuminized fogersite, and mesoporous silicate. A method and apparatus for manufacturing high concentration ozone gas, characterized by employing a TSA adsorbing system, discharging oxygen concentrated gas at a relatively low temperature from the adsorbing layers, passing purge gas at a relatively high temperature into the adsorbing layers in the desorbing process in an opposite direction of the gas flow in the adsorbing process, and recovering the concentrated ozone gas continuously, in which the ozone adsorbent is one or two or more kinds of above adsorbent, and the gas containing ozone from the ozone generating apparatus is cooled by the oxygen concentrated gas at a relatively low temperature flowing out from the adsorbing layers in the adsorbing process.
